Cant add or remove widget

Hi!

On widgets tab, I cannot drag and drop widgets to sidebars/footers or remove them from there.
I already had this issue and it was solved by installing "Use google libraries" plugin. But now widgets doesn't work even with this plugin.

If I change my theme to default - everything works great.

Any help?
