I just installed 1.23.3 using Softaculous. I am seeing an error in my log: PHP Fatal error: Call to a member function getTitle() on a non-object in /home/rulemlso/public_html/wiki.ruleml.org/includes/Feed.php on line 309 This error message seems odd because line 309 in Feed.php reads return gmdate( 'D, d M Y H:i:s \G\M\T', wfTimestamp( TS_UNIX, $ts ) ); There is no obvious affect on the wiki itself - I'm not really sure where to look for it. I have the following extensions installed: Multi-Category Search (1.66) Replace Text (1.0) Cite (-) ParserFunctions(1.6.0) Privacy(1.2.3) SyntaxHighlight(1.0.8.11-wmfm1) Lockdown (d08bc8) WikiEditor (0.4.0) PHP is 5.3.29 (litespeed) MYSQL is 5.5.36-cll-lve
Thanks for taking the time to report this! http://www.mediawiki.org/wiki/Manual:How_to_debug might help to get a bit more info, and I'd also recommend to ask on https://www.mediawiki.org/wiki/Project:Support_desk
Tara: Did you ask on the support desk? Could you link to that request?
Yes. https://www.mediawiki.org/w/index.php?title=Project:Support_desk&offset=20140914030551&limit=20#PHP_Fatal_errors_after_installing_Version_1.23.3_47970

"The errors seem to have disappeared on their own, so this seems like a likely culprit."
I was mistaken about the errors disappearing - I was just looking for them in the wrong place. The errors continue to appear, at a rate of between 2-8 times per day, in the error_log file in my wiki directory.
A stack trace would be useful for debugging this further. Can you add "$wgShowExceptionDetails = true;" (without the ") to your LocalSettings.php?

I have added $wgShowExceptionDetails = true; to LocalSettings.php Where do I look for the stack trace?
Based on my webhost's suggestion, I added $wgCacheEpoch = '20140924154644'; to my LocalSettings.php This has had no effect on the errors.
(In reply to taraathan@gmail.com from comment #9) > I have added $wgShowExceptionDetails = true; to LocalSettings.php > Where do I look for the stack trace? https://www.mediawiki.org/wiki/Manual:How_to_debug states that more details (like a stack trace) should be shown on the "Fatal error" page itself.
So far I haven't figured out what the page is that triggers this "Fatal error". The frequency pattern in the log file, and the absence of users reporting problems, suggests that it happens when some bot is crawling our site.
