Interesting thing happening in quick reply window. If I turn on WYSIWYG I can mention other users (after type @ opening a suggestion box), but I can't quote selected text (selected text not appearing in quick reply window and I get this error:
Uncaught TypeError: Cannot read property '0' of undefined jquery.sceditor.bbcode.min.js:2
Uncaught TypeError: Cannot read property '0' of undefined 6jquery.sceditor.bbcode.min.js:3
BUT when I turn off WYSIWYG on my forum profile I can quote selected text, but cannot mention other members (suggestion box not appearing) and I got this error:
Uncaught TypeError: this.$inputor.caret is not a function jquery.atwho.min.js:1
Strange, isn't it?
I'm using Beta 2 (also I updated all JS files to latest). Do not have any mods.
