Press F12 and check for js errors in your browser console.

Do you use an optimizer of any kind (a plugin) ?

I didn't say to use optimizer to solve your problem. I ment to remove it.

Also i said press F12 and check for errors.

Anyways, since you found the cause (your theme) maybe ask them for some help.

Hi @bcpovo,

The issue doesn't come from the wpForo plugin for sure. You should contact the SuperMag theme support forum and ask them to check and solve the issue.
