This time I am not having problem activating/deactivating the add ons.
Yes I had 3 columns with masonry and when I updated it was 2 with some space left. It work with 3 only if I uncheck the masonry. The site is jobseekeritalia.it
No cache on my end – cleared it and tried incognito. Also looked at the code and it all checks out. Have you cleared your browser cache? Any caching plugins?
