Thread:Extension talk:WYSIWYG/IE11 with MW 1.22.0 + WYSIWYG extension: Existing category definitions will corrupt after after page has been saved/reply (4)

I tried my installation (#6) only with IE8, but it does not work for some reason: page with bulleted or numbered list will become empty when mode is changed from wysiwyg to wikieditor. If list is created in wikitext mode and then switched to wysiwyg it works. I tried to cancel this modification, but it did not help, result was the same with IE8. I think it must be some other kind of problem but I could not find where the problem is :(.
