Category filters are working but attribute filter checkboxes are all disabled. I'm 99% sure they were working before but probably after an update or perhaps a product added by the user caused a conflict.

I've looked trough the filter settings but could not find any cause for this issue.

Hope someone can help us out.

Cheers,
WJ

Try changing the template to Cassiopeia – Default on a backup copy of the site, and then check if the filters work. If the filters start working, it means the problem is in the template.
