2 days ago, something strange happened to my forum. All of the sudden, some of the javascript features just stopped working. For example, forum navigation (old nav_quick_links, with show/hide function) just shrink (like it should) when hide button is pressed, but rest of the forum layout stays fixed! No auto resize forum blocks. Here is screenshot.


Furthermore, on posting page, smileys can't be inserted, none of the bbcodes (above writing area) don't work (they work, if entered manually), even text color chooser don't work.
On the other hand, categories of forums can be shown/hidden correctly, Lightbox javascript for images works normal, and I didn't noticed some other java things to fail (ajax features work correctly, etc.).
Here is the link to my forum, so you guys can check it out. Is this some kind of bug, or it's something else? Version of Icy is 10.11.11, and nothing is uploaded, or changed at the time this happened.
If I can provide you with any other info I forgot to mention here, just ask.
Thanx
