   1 # Troubleshooting
   2
   3 First of all, ensure that both the [web server](Server-configuration.md) and [Shaarli](Shaarli-configuration.md) are correctly configured.
   4
   5
   6 ## Login
   7
   8 ### I forgot my password!
   9
  10 Delete the file `data/config.json.php` and display the page again. You will be asked for a new login/password.
  11
  12 ### I'm locked out - Login bruteforce protection
  13
  14 Login form is protected against brute force attacks: 4 failed logins will ban the IP address from login for 30 minutes. Banned IPs can still browse Shaares.
  15
  16 - To remove the current IP bans, delete the file `data/ipbans.php`
  17 - To list all login attempts, see `data/log.txt` (succesful/failed logins, bans/lifted bans)

  21 ## Browser issues
  22
  23 ### Redirection issues (HTTP Referer)
  24
  25 Shaarli relies on `HTTP_REFERER` for some functions (like redirects and clicking on tags). If you have disabled or altered/spoofed [HTTP referers](https://en.wikipedia.org/wiki/HTTP_referer) in your browser, some features of Shaarli may not work as expected (depending on configuration and installed plugins), notably redirections between pages.
  26
  27 Firefox Referer settings are available by browsing `about:config` and are documented [here](https://wiki.mozilla.org/Security/Referrer). `network.http.referer.spoofSource = true` in particular is known to break some functionality in Shaarli.
  28
  29
  30 ### Firefox, localhost and redirections
  31
  32 `localhost` is not a proper Fully Qualified Domain Name (FQDN); if Firefox has been set up to spoof referers, or only accept requests from the same base domain/host,
  33 Shaarli redirections will not work properly. To solve this, assign a local domain to your host, e.g. `localhost.lan` in your [hosts file](https://en.wikipedia.org/wiki/Hosts_(file)) and browse Shaarli at http://localhost.lan/.
  34
  35 -----------------------------------------
  36
  37 ## Hosting problems
  38
  39 ### Old PHP versions
  40
  41 On **free.fr**: free.fr now supports php 5.6.x([link](http://les.pages.perso.chez.free.fr/migrations/php5v6.io))
  42 and so support now the tag autocompletion but you have to do the following.
  43
  44 At the root of your webspace create a `sessions` directory and a `.htaccess` file containing:
  45
  46 ```xml
  47 <IfDefine Free>
  48 php56 1
  49 </IfDefine>
  50 ```
  51
  52 - If you have an error such as: `Parse error: syntax error, unexpected '=', expecting '(' in /links/index.php on line xxx`, it means that your host is using php4, not php5. Shaarli requires php 5.1. Try changing the file extension to `.php5`
  53 - On **1and1** : If you add the link from the page (and not from the bookmarklet), Shaarli will no be able to get the title of the page. You will have to enter it manually. (Because they have disabled the ability to download a file through HTTP).
  54 - If you have the error `Warning: file_get_contents() [function.file-get-contents]: URL file-access is disabled in the server configuration in /…/index.php on line xxx`, it means that your host has disabled the ability to fetch a file by HTTP in the php config (Typically in 1and1 hosting). Bad host. Change host. Or comment the following lines:
  55
  56 ```php
  57 //list($status,$headers,$data) = getHTTP($url,4); // Short timeout to keep the application responsive.
  58 // FIXME: Decode charset according to charset specified in either 1) HTTP response headers or 2) <head> in html
  59 //if (strpos($status,'200 OK')) $title=html_extract_title($data);
  60 ```
  61
  62 - On hosts which forbid outgoing HTTP requests (such as free.fr), some thumbnails will not work.
  63 - On **lost-oasis**, RSS doesn't work correctly, because of this message at the begining of the RSS/ATOM feed : `<? // tout ce qui est charge ici (generalement des includes et require) est charge en permanence. ?>`. To fix this, remove this message from `php-include/prepend.php`
  64
  65 ### Dates are not properly formatted
  66
  67 Shaarli tries to sniff the language of the browser (using `HTTP_ACCEPT_LANGUAGE` headers)
  68 and choose a date format accordingly. But Shaarli can only use the date formats
  69 (and more generally speaking, the locales) provided by the webserver.
  70 So even if you have a browser in French, you may end up with dates in US format
  71 (it's the case on sebsauvage.net :-( )
  72
  73 ### My session expires! I can't stay logged in
  74
  75 This can be caused by several things:
  76
  77 - Your php installation may not have a proper directory setup for session files. (eg. on Free.fr you need to create a  `session` directory on the root of your website.) You may need to create the session directory of set it up.
  78 - Most hosts regularly clean the temporary and session directories. Your host may be cleaning those directories too aggressively (eg.OVH hosts), forcing an expire of the session. You may want to set the session directory in your web root. (eg. Create the `sessions` subdirectory and add `ini_set('session.save_path', $_SERVER['DOCUMENT_ROOT'].'/../sessions');`. Make sure this directory is not browsable !)
  79 - If your IP address changes during surfing, Shaarli will force expire your session for security reasons (to prevent session cookie hijacking). This can happen when surfing from WiFi or 3G (you may have switched WiFi/3G access point), or in some corporate/university proxies which use load balancing (and may have proxies with several external IP addresses).
  80 - Some browser addons may interfer with HTTP headers (ipfuck/ipflood/GreaseMonkey…). Try disabling those.
  81 - You may be using OperaTurbo or OperaMini, which use their own proxies which may change from time to time.
  82 - If you have another application on the same webserver where Shaarli is installed, these application may forcefully expire php sessions.
  83
  84
  85 ### Old apache versions, Internal Server Error
  86
  87 If you hosting provider only provides apache 2.2 and no support for `mod_version`, `.htaccess` files may cause 500 errors (Internal Server Error). See [this workaround](https://github.com/shaarli/Shaarli/issues/1196#issuecomment-412271085).
  88
  89
  90 ### Sessions do not seem to work correctly on your server
  91
  92 Follow the instructions in the error message. Make sure you are accessing shaarli via a direct IP address or a proper hostname. If you have **no dots** in the hostname (e.g. `localhost` or `http://my-webserver/shaarli/`), some browsers will not store cookies at all (this respects the [HTTP cookie specification](http://curl.haxx.se/rfc/cookie_spec.html)).
  93
  94 ----------------------------------------------------------
  95
  96 ## Upgrades
  97
  98 ### You must specify an integer as a key
  99
 100 In `v0.8.1` we changed how Shaare keys are handled (from timestamps to incremental integers). Take a look at `data/updates.txt` content.
 101
 102
 103 ### `updates.txt` contains `updateMethodDatastoreIds`
 104
 105 Try to delete it and refresh your page while being logged in.
 106
 107 ### `updates.txt` doesn't exist or doesn't contain `updateMethodDatastoreIds`
 108
 109 1. Create `data/updates.txt` if it doesn't exist
 110 2. Paste this string in the update file `;updateMethodRenameDashTags;`
 111 3. Login to Shaarli
 112 4. Delete the update file
 113 5. Refresh
 114
 115
 116
 117 --------------------------------------------------------
 118
 119 ## Import/export
 120
 121 ### Importing shaarli data to Firefox
 122
 123 - In Firefox, open the bookmark manager (`Bookmarks menu > Show all bookmarks` or `Ctrl+Shift+B`), select `Import and Backup > Import bookmarks in HTML format`
 124 - Make sure the `Prepend note permalinks with this Shaarli instance's URL` box is checked when exporting, so that text-only/notes Shaares still point to the Shaarli instance you exported them from.
 125 - Depending on the number of bookmarks, the import can take some time.
 126
 127 You may be interested in these Firefox addons to manage bookmarks imported from Shaarli
 128
 129 - [Bookmark Deduplicator](https://addons.mozilla.org/en-US/firefox/addon/bookmark-deduplicator/) - provides an easy way to deduplicate your bookmarks
 130 - [TagSieve](https://addons.mozilla.org/en-US/firefox/addon/tagsieve/) - browse your bookmarks by their tags
 131
 132 ### Diigo
 133
 134 If you export your bookmark from Diigo, make sure you use the Delicious export, not the Netscape export. (Their Netscape export is broken, and they don't seem to be interested in fixing it.)
 135
 136 ### Mister Wong
 137
 138 See [this issue](https://github.com/sebsauvage/Shaarli/issues/146) for import tweaks.
 139
 140 ### SemanticScuttle
 141
 142 To correctly import the tags from a [SemanticScuttle](http://semanticscuttle.sourceforge.net/) HTML export, edit the HTML file before importing and replace all occurences of `tags=` (lowercase) to `TAGS=` (uppercase).
 143
 144 ### Scuttle
 145
 146 Shaarli cannot import data directly from [Scuttle](https://github.com/scronide/scuttle).
 147
 148 However, you can use the third-party [scuttle-to-shaarli](https://github.com/q2apro/scuttle-to-shaarli)
 149 tool to export the Scuttle database to the Netscape HTML format compatible with the Shaarli importer.
 150
 151 ### Refind.com
 152
 153 You can use the third-party tool [Derefind](https://github.com/ShawnPConroy/Derefind) to convert refind.com bookmark exports to a format that can be imported into Shaarli.
 154
 155
 156 -------------------------------------------------------
 157
 158 ## Other
 159
 160 ### The bookmarklet doesn't work
 161
 162 Websites which enforce Content Security Policy (CSP), such as github.com, disallow usage of bookmarklets. Unfortunately, there is nothing Shaarli can do about it ([1](https://github.com/shaarli/Shaarli/issues/196), [2](https://bugzilla.mozilla.org/show_bug.cgi?id=866522), [3](https://code.google.com/p/chromium/issues/detail?id=233903).
 163
 164 Under Opera, you can't drag'n drop the button: You have to right-click on it and add a bookmark to your personal toolbar.
 165
 166
 167 ### Changing the timestamp for a shaare
 168
 169 - Look for `<input type="hidden" name="lf_linkdate" value="{$link.linkdate}">` in `tpl/editlink.tpl` (line 14)
 170 - Replace `type="hidden"` with `type="text"` from this line
 171 - A new date/time field becomes available in the edit/new Shaare dialog.
 172 - You can set the timestamp manually by entering it in the format `YYYMMDD_HHMMS`.
