Hello,

I discovered one more think - i cannoct see editor for localhost too if i swith in IE to Compatibility view. I can see editor if i "unswitch" compatibility view. 

I also try to switch and unswitch for server, but no change - editor is still not showed.

I also try to click on server "Show RichTextEditor" but without change - editor is not showed.

Then I comment couple lines in config.js and now i can see editor. You can recognize my comment (//) that they are on the biggining of rows. But there starts new problem - text is completelly broken if i edit something in editor (i think that this is because i comment some important thinks). So i bring changes back and again i cannoct see editor :-(
