Warning during install + creating widget page identified as harmful
Fragment of a discussion from Extension talk:Widgets
Looks like first one is not related to Widgets, but to diff - check $wgDiff setting in your LocalSettings.php and if the file exists and allowed for execution. Once again, it's not related to Widgets extension.
The warning about HTML markup seems to originate from AbuseFilter extension you have installed. Try to figure out how to configure it to ignore "Widgets" namespace.
Let me know if that helps. --Sergey Chernyshev 19:51, 2 July 2010 (UTC)
