Thread:Project:Support desk/several wikis stopped working spontaneously

I've got several wikis that have worked fine for a few weeks now. They were working fine earlier today, and now all of a sudden they don't. All but one says this: MediaWiki internal error./Exception caught inside exception handler./Set $wgShowExceptionDetails = true; at the bottom of LocalSettings.php to show detailed debugging information. so I did that and get this error: Parse error: syntax error, unexpected $end in /home/argument/public_html/w/LocalSettings.php on line 139. Except for one of the wikis, which has a completely different error message: Something similar happened awhile ago but the sites started working again randomly. What's going on? (other wikis not working: one, which is basically a bare installation I've barely used, this one, this one, this one and this one. Modrobene 06:15, 10 December 2011 (UTC)
