It shows up in the access log as a 500, e.g. [IP number] - - [13/Oct/2012:08:59:18 -0400] "GET /wiki/Special:Watchlist HTTP/1.1" 500 308 "http://rationalwiki.org/wiki/RationalWiki:Technical_support"; "[browser agent string]" - that apparently renders blank. This doesn't show anything in the Apache or PHP error log around this time either. Most frustrating ... I've turned up the logging a bit. - d. _______________________________________________ MediaWiki-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
