Thread:Project:Support desk/1.17+ backwards-compatibility with IE7/reply (2)

If MediaWiki 1.20 is having issues in IE7, it is likely something related to your configuration. Because to my knowledge no MediaWiki version since 1.17 (1.18, 1.19, 1.20, 1.21 and – currently in development and deployed to MediaWiki.org and Wikipedia – 1.22) has issues with IE7.

The bug you describe (javascript not working on the preferences page) suggests there may be a different (IE7 incompatible) script being loaded that causes MediaWiki's script to no longer execute.

Either way, please report the bug, if it is caused by MediaWiki I'm sure we'll do our best to find a solution because it sure was not an intentional decision for javascript to break fatally in IE7 in MediaWiki 1.20. There are no known bugs like the one you describe in IE7.
