Move wiki to new server with current MW, Fatal PHP error

 * MediaWiki version: 1.13.3
 * PHP version: 5.1.6-20
 * MySQL version: 5.0.45-7
 * URL: Classified (very literally, not a joke! ;-) )
 * OS: RHEL5

I need to move a wiki (1.10.0) from one machine to another, and at the same time upgrade MW to 1.13.3 After untarring MediaWiki, copying the contants of /images and restoring the database, attempting to access the wiki results in an error:

[Tue Jan 20 19:48:14 2009] [error] [client 192.168.1.2] PHP Fatal error: require_once [function.require]: Failed opening required '/var/www/html2/wiki/ LocalSettings.php' (include_path='.:/usr/share/pear:/usr/share/php') in /var/www/html2/wiki/ includes/WebStart.php on line 97

Strange behaviour after install, PHP problem?

 * MediaWiki version: 1.13.2
 * PHP version: 5.2.6
 * MySQL version: 5.0.45
 * URL: http://www.mikakunii.net/mikawiki

A very strange behaviour of wiki after install: articles are not shown at all although content is present: try edit to see that its present, or follow http://www.mikakunii.net/MikaWiki that is working on the same database (that 2nd wiki was istalled after that problem did appear on the 1st).

During install process I had some warnings ( intall_log.txt for complete reference): I tried asking my hosting service assistance and they told me that the cause maybe was more due an error configuring mediawiki than a server problem. I installed same version on a localhost doing the same install procedure and everything has gone well so I suppose its a PHP error and not a configuration error, maybe am I wrong? I don't think its a mysql issue as the 2nd installation of mediawiki works good on the same database. And as the install procedure build everything was necessary I thought also its more concerning PHP than a installation error itself.

Notice warning during install procedure:

Warning: is_dir: open_basedir restriction in effect. File(/opt/pieroni/php5/session) is not within the allowed path(s):(/var/www/vhosts/mikakunii.net/httpdocs:/tmp) in /var/www/vhosts/mikakunii.net/httpdocs/mikawiki/config/index.php on line 438 Warning: Your session.save_path value (/opt/pieroni/php5/session) appears to be invalid or is not writable. PHP needs to be able to save data to this location for correct session operation.

Maybe this is the main problem or a sign of a lack of PHP config on server? Please help me, thank you. I tried to do my best... but can't solve this alone. --Federicodip 18:47, 15 December 2008 (UTC)

Permission problem with Apache: cannot reproduce in Apache debug mode

 * MediaWiki version: 1.13.3
 * PHP version: 5.2.6-5
 * MySQL version: 5.0.67-2
 * URL:

I'm using Apache 2.2.10-2. If I run Apache as a service on my Linux box, I get PHP permission errors in the HTTPD logs:

PHP Warning: Unknown: failed to open stream: Permission denied in Unknoxn on line 0 PHP Fatal error: Unknown: failed opening required '/var/www/html/mediawiki/index.php' (include_path='.:/usr/share/pear:/usr/share/php') in Unknown on line 0

However if I start Apache in debug mode with

> /usr/sbin/httpd -X

Mediawiki works fine. The httpd process is running under the same UID (apache) both times. Any ideas? Thanks.

 * Assuming you're running PHP as an Apache module, the Apache user needs to be able to read the entire /mediawiki directory. /var/www is usually owned by the Apache user anyway, but if not, make it readable to all:
 * If you're in a multi-user environment, then you should be a bit more cautious:

Strange error after backuping

 * MediaWiki version: 1.13.3
 * PHP version: 5.2.6
 * MySQL version: 5.0.45
 * URL: http://web223.sydney.webhoster.ag/user/david_b/homepages/vwikika

Hey guys, I installed the backup-script of http://www.mediawiki.org/wiki/User:Flominator/Backup_MW and it works. Then I tried to exec it with a cronjob. I entered the command on my web-interface. Minutes later I want to log in to my Wiki as the error (see below) appeared. The cronjob hasn't been started yet! I absolutely don't know what to do. MediaWiki crashes in reason of copying files?!

Thank you for your help! David

THE ERROR:

 * Re-upload all the wiki files. Rerun the installer or manually recreate LocalSettings.php if you destroyed your copy. —Emufarmers(T 04:28, 16 January 2009 (UTC)


 * I re-upload all files and it works. Thank you! But isn't this strange? I mean I didn't change any files and the wiki chrashed ^^

 * Are you sure you only exported that one page? If so, temporarily increase max_execution_time in php.ini, or use another import method. —Emufarmers(T 22:17, 27 January 2009 (UTC)

How to Avoid 'Login Required' Error page.
I've setup a private internal mediawiki with users unable to create accounts (admin only). I can't figure out how to avoid (or redirect) the 'Login Required' error page and have the Login page (Special:Userlogin) be the first page up (and then modify its text to welcome users, etc).
 * MediaWiki version: 1.13.3
 * PHP version: 5.0.67
 * MySQL version: 5.0.16
 * URL: gefsr.com 

The only suggestion I've found is to use this in LocalSettings.php : $wgRedirectMustLogin = true; $wgRedirectLoggedIn = true; neither of which work (though I did manage to redirect the useless 'you are now logged in' page to the main page).

Or, perhaps there's a way to include login within the MainPage? (and then whitelist the main page)

I'm a beginner, thanking you in advance!

500 Internal Server Error (only on one single page)

 * MediaWiki version: 1.13.3
 * PHP version: 5.2.6
 * MySQL version: 5.0.45
 * URL:

Hi, I just found some Threads with the similar topic but I didn't find a solution yet.

The following errors occurs only on one (didn't find another ^^) page:

'' Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. ''

I don't have access to my php.ini. Tried to active logs by using the LocalSettings.php but it didn't works.

Any idea :/ ?

Problem solved! The reason was a category which was subcategory of itself. Each page which was categorized with this category responsed with an error. Also the category page itself.

I deleted the relevant row in the SQL "Category links" table and now it works again...

We have been using MediaWiki for about a month with no problems. Over the last two days something has changed. Even though we have not changed any of our settings. Primarly IE7 has problems loading pages about every 10th time.
