I get this message:
Set $wgShowExceptionDetails = true; at the bottom of LocalSettings.php to show detailed debugging information.
When it happens
It's happening tonight when I try to save edits of talk pages on Wikitravel, such as a user talk page and the Travellers' Pub.
What should happen
I should be able to save edits!
How to fix it
Beats me; that's your department. I'm not a techie; I just edit and add content.
Wikitravel is the slowest I've ever experienced, excluding days when no editing could be done at all.
