Error when trying to edit wiki pages

[chuzzum]

Whenever I try and make an edit to a page, I get the following error:

Internal error
Set $wgShowExceptionDetails = true; at the bottom of LocalSettings.php to show detailed debugging information.

It happens even when I am logged into my account. Does this occur for anyone else as well?

Wiki editing is broken at the moment. We are waiting on an upgrade of the software base, due in (possibly) June.

Any update on that update?

As an aside -- editing does work now, the only thing is that the CSS has gotten messed up.

We're on MediaWiki 1.18.3 -- I don't happen to know where this version keeps stuff, but as I get some time, I will browse around and see if there's some obvious file-moving I need to do to get the styles working.

I know there are mailing lists for MW. If it's not immediately obvious, might save a lot of time just to ask.
