Pulling my hair with this strange issue. When I want to insert link in wordpress page or post, my whole page screen is greyed out, and insert link feature dont work. I tried to disable plugins, insert fresh files for tinymce, install several others editors... But, nothing. Issue is same on both, visual and html editor.

Looks like you need to update jQuery. You are running

/*! jQuery v1.8.3 jquery.com | jquery.org/license */

and a very quick search of the error message text lead to this, posted five months ago-- https://github.com/blueimp/jQuery-File-Upload/issues/1794--, and to the simple instructions "You need to upgrade to jquery-ui 1.9".

I would suggest updating your install as a whole: http://www.redcoats.co.uk/readme.html
