Hello,
thank you for the answer! Unfortunately it did not solve the problem, I deleted and then reinstalled the plugin, but it looks the same on my side.
I also made a new grid, but the issue is the same.. here it should be a 3 column masonry grid, but I see 1 full-width instead.. https://pneumaszov.org/teszt-work/
I tested it in different browsers.
Do you happen to have any other idea what could cause this problem?
thanks a lot,
luca
