The wordpress 4.2.3 seems to be the only difference between the two sites. The older site (where the menu works correct) runs wordpress 4.2.2.

Whenever i select ‘set as active’ or ‘keep changes’ it reloads the page and doesn’t save.

I have also seen another topic where the solution was to reupload the theme via FTP, i tried this but still no solution. In this post below i will leave the site credentials so you can check it out. So far you guys have been a great help and i know some staff members are on vacation, however a quick solution would be much appriciated.

Bump

It’s fixed now. Don’t know exactly what caused it but it might have something to do with:

1. Activated JetPack responsive module (from old theme)

2. Activated responsive Specular

You can close this topic now.
