When I go to a category page on my Magento installation since a couple of weeks I do not have a working search/mobile menu/language switcher:


When trying to switch the language in a category it adds a # and doesn't open the JavaScript that is needed. When on Homepage/CMS page/Product page everything works great.

I cannot figure out where the bug is taking place. The Console doesn't tell me enough.

In your category page, I get this error in the console TypeError: jQuery(...).owlCarousel is not a function common.js (line 42, col 2).
I think this error occurs before the bootstrap js can do its magic so the whole js execution stops.
Try to remove the occurrences of owlCarousel from common.js and see what happens.
