Thread:Project:Support desk/Mediawiki skins and editor toolbar not working on new installation

I just installed Mediawiki 1.19.3 RPM as downloaded from EPEL. I am using PHP 5.3.3. MySQL 5.1.67.

The skins that are shipped with Mediawiki, such as standard, monobook, etc do not work. The error I get is: Class SkinStandard not found; skipped loading Class PEAR_Error not found; skipped loading

Curiously enough, if I try to use my custom skin, the errors go away. This is surprising since all of the skins, including my custom skin, are at /var/www/mediawiki119/skins. I would have expected my custom skin to break, not the Mediawiki skins.

Secondly, using my custom skin, the editor will not display the toolbar. And the error in the log is: Class SkinMda not found; skipped loading Class PEAR_Error not found; skipped loading

Note, Mda is the name of my custom skin. So it is obvious that there is something wrong somewhere that is preventing Mediawiki from seeing the skins from the editor page. The only reports of this problem I can find are to link /var/www/mediawiki119/skins to /usr/share/mediawiki119/skins, which I have already done. And since my custom skin works, except from the editor, I assume I have everything in the correct place.

Also note that php-pear is installed, so I do not know why I am getting the PEAR_Error error message either.

Thanks in advance for your help.
