[14:16:04] <JolanW>	 Whenever I go to edit a page on my mediawiki instance, after installing 1.44, I get 'Exception caught: class "Title" not found'. I thought this was an issue with the new heading parser, so I set $wgParserEnableLegacyHeadingDOM to TRUE in my LocalSettings.php, and the issue persists.  
[14:17:13] <JolanW>	 I'm using the Citizen skin, I thought it might be an issue there, but I'm not seeing any issues with that skin since 1.44.

[14:22:02] <andre>	 JolanW, see https://www.mediawiki.org/wiki/Manual:How_to_debug how to get a stacktrace
[14:25:11] <Reedy>	 Chances are you haven't updated a skin/extension, and/or the skin/extension hasn't been updated for 1.44
[14:29:23] <JolanW>	 thanks andre, I have wgShowExceptionDetails on, but I'm not getting a stack trace because it's an exception caught. I'll turn on wgShowDebug to get some more detailed log msgs 
[14:29:38] <JolanW>	 I think Reedy is right that this is an issue with not updating skins/extensions
[15:16:30] <RhinosF1>	 Reedy: based our testing, there's a fair few extensions that weren't updated in time
[15:16:49] <RhinosF1>	 Unfortunately Miraheze was late starting testing and most it only happened after 1.44.0 was out
[15:17:30] <RhinosF1>	 We are fixing what we find
