JQuery crashed after WP major update and settings no saving

Hi there,

I’ve experiencing several problems after the WordPress update. Today I’ve found a new one:

When I try to change some settings at the Options Panel the submit button didn’t work. I’ve inspected that button and found that have some missfunctions at the JQuery. Every button that need JS is not working. So, I’m kind locked here with my development.

And I’ve already discussed with Hristina about other minor bugs.

If someone could help I’ll be thankful!
