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

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:

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:

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

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!

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

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.

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...

Update

In my whole life I only wrote a few lines of php code. So I don't know much about php code but anyway I looked into the code:

First I read on the internet, that the ArrayIterator constructor is not public and you have to use getIterator on an ArrayObject. But if it is still true, I'm confused most ppl have no problems.

But there is more. “return new ArrayIterator( explode( $separator, $subject ) )” looks like endless recursion.

dumpBackup.php error - tries to use root even with LocalSettings.php

 * MediaWiki version: 1.14
 * PHP version: 5.1.6
 * MySQL version: 5.0.45
 * URL: Intranet only

I have a AdminSettings.php in my maintenance folder (created from the template in the wiki directory) that contains database connection user and password. The scripts in the Maintenance folder that I have tried run successfully, including scripts that seem to be getting information from the database, however dumpBackup.php will not run successfully.

When I run  it says. It is not getting the db connection information from AdminSettings.php. AdminSettings.php is owned by apache:apache, and I have tried setting to 660, 770, 666, 777, with no change. It is now set back to 600, and other scripts seem to be still working fine.

I have got around the issue by placing $wgDBadminuser and $wgDBadminpassword lines (copied exactly from AdminSettings.php) directly into a copy of dumpBackup.php. It then works fine.

Any ideas why it won't work as it's intended to?

Fatal error: Class 'ArrayIterator' not found in /usr/local/www/apache22/data/wiki/includes/StringUtils.php on line 179
I got this error on my FreeBSD 7.1 system, directly after moving the LocalSettings.php file. The solution provided in this section did not solve the problem in my case.
 * MediaWiki version: 1.14.0
 * PHP version: 5.2.8
 * MySQL version: 5.0.67
 * URL: internal link

I edited the StringUtils.php page from line 179 to skip using the ArrayIterator. I edited the 'else' part to test.

Note that my wiki shows at this point. Before I only got a browser http 500 error message with the fatal error in the (apache22) web server error log.

I noticed also the class for the ArrayIterator is not present in the file like the class for ExplodeIterator.

Now I can see the main page, but it only shows the main heading and it looks I can edit but not save the edited pages (or the fonts are white?) In the error log I notice more errors.

Hope part of this info helps finding out the actual problem here.

Blank login page and php error cannot redeclare class skintemplate

 * MediaWiki version: 1.14.0
 * PHP version: 5.2.6 (apache2handler)
 * MySQL version: 5.0.77
 * URL: Internal Only

I'm outside of my scope of experience here so please phrase your answers without assuming I know lots of things (I haven't even really begun to understand the levels of dependencies).

I have successfully installed Mediawiki on a local box and had successfully created and edited some pages. I had also successfully uploaded images to some of those pages.

All of a sudden whenever I try to upload an images I get told I have to login, however when I go to the login/create account page it's just blank.

I checked the httpd logs and found the following message......

[error] [client 192.168.1.12] PHP Fatal error: Cannot redeclare class SkinTemplate in /var/www/html/wiki/includes/SkinTemplate.php on line 997, referer: http://192.168.1.240/wiki/index.php?title=Special:Upload&wpDestFile=someimage.jpg

I've looked at SkinTemplate.php and line 997 doesn't have a redeclare command (I'm not really sure what this is doing as this is well outside my experience zone)...

The code block near to line 997 is......

However it's the very last } that's actually on line 997, I'm assuming that the last } causes the commands to be executed and that's why the error is flagging up there.

If anyone could give me some pointers I'd be very grateful as I'm stuck here and because I don't understand the dependencies I could spend hours trying to solve what may be a trivial fault.

Thanks in advance.

Fatal error when trying to create a modified monobook theme

 * MediaWiki version: 1.14.0
 * PHP version: 5.2.6
 * MySQL version: 4.1.25
 * URL: removed for now.

What I am trying to accomplish is to create a slightly modified version of the monobook theme. Steps: 1) I made a copy of the Monobook.php, MonoBook.deps.php, and monobook folder. 2) Replaced all instances of 'Monobook' or 'monobook' (aware of case-sensitivity) with 'Greencurrent' or 'greencurrent' within the copied files and renamed the files themselves.

The result is a fatal error:

Fatal error: Class 'GreencurrentSkinTemplate' not found in [serverpath]/html/wiki/includes/SkinTemplate.php on line 128

While I would love to resolve this, I am equally keen to know how I would go about debugging this myself!
