We just looked at your web-site and don’t see masonry categories on your home page and console without any errors, do you still have this problem? Could you provide your admin access so we can replicate the issue?
We still can’t enter your admin access. But we found the problem. You are using plugin “furnde-vc-addons” that rewrites our “Isotope” library and cause this conflict. Try to disable this plugin. If you still want to use so provide us your FTP details and we will fix this conflict on your web-site in the child theme.
