The filters are performing very slow, while the server should have more then enough performance.
It takes about 4 seconds to get the filter ready.
But sometimes I also get “pjax error timeout” and then the pages refreshes (in that case we have 2 times a slow process).
Are the filters made efficient and are the filters cached/indexed in an efficient wat?
Or are the default WordPress methods used for querying with the filters?
Please, confirm the permission for plugins deactivation, and switching to the parent/default theme. As soon as we complete the testing we will enable it all back.
Please clone your website and move it to the staging platform so I can investigate the issue there and in such a way your main website will not be affected.
