TinyMCE Insert Link Not Working for Media Library

I just upgraded my local installation from v7.6.14 to v7.15.7. When I try to insert a link to a document from the Media section, it populates the Link title field but it grays out the Link url field. When i click submit, there is no link.

I’m also having issues When i try to insert an image using the media picker. It lets me select an image but when I click Insert, it’s inserting paragraphs tags and no image.

I’m guessing there’s something wrong with my tinymce file but I’m not sure what to check.

Any suggestions?
