Blank as in no content in empty skin or blank as in white screen of death? If the latter, check the error logs. Also, try disabling extensions to troubleshoot.

Now, aside from the main page, I get only blank pages. The only thing that I can think of that it has to do with the fact that I have this: $wgGroupPermissions['*']['edit'] = false; $wgGroupPermissions['*']['read'] = false; $wgGroupPermissions['user']['edit'] = true; set in LocalSettings.php and that it's a cookie or other auth thing. Ideas?

Killed firefox and now get a blank for the Main page as well. Ideas? Don't care to roll back (mostly because I live in fear of MySQL).

WSOD, apparently. No extensions other than what ships with the tarball.

Searching for logs now ...

[Mon Jun 23 14:58:12 2008] [error] [client 10.197.0.114] PHP Fatal error: Class 'DOMDocument' not found in /data/wiki/includes/Preprocessor_D OM.php on line 566, referer: http://myhost/wiki/index.php/Main_Page

Gee, this wouldn't have anything to do with it, would it??? :-)

What is a 'DOMDocument' and where would I get one?

It should be compiled into your PHP. What OS and version of PHP are you running?

RHEL 5.2 php-5.1.6-20.el5

All this worked under 1.10.1 (this morning) and MW really is the only thing I've changed (no, "well except for ...").

the problem is related specificaly to v1.12.0

There is a quick fix - add to LocalSettings.php: $wgParserConf['preprocessorClass'] = 'Preprocessor_Hash';

The "permanent" fix is to install the 'php-xml' package and restart Apache: # yum -y install php-xml (on fedora anyway) # service httpd restart

Actually, I found the "permanent" fix was quicker to implement than the quick fix 8^) ...but I tested each and both worked (for me)

the reference is (watch out for the line wrapping): http://www.mediawiki.org/wiki/Project:Support_desk#.28RESOLVED.29_PHP_Fatal_...

That was exactly it. Fixed. Permanently. Thanks for the quick replies!!
