None of the plugins are the issue. I've already gone through them and disabled them all except for toolset and wp bakery page builder. Last time I checked the functionality of this search would be about two weeks ago and it was fine then. I have not added any new plugins in that time frame.
I will have to give you new credentials. I do not know why it is not working anymore. I do not know how to set a private message or to edit the previous private message
What I recommend that you do is to remove all your filters and re-add them back to the search because the URL parameter that they should be using do not match up to what the query filter is looking for.
Removing and re-adding them should fix this issue for you.
Still a strange problem - when a search filter is chosen - the pagination does not change.
for example --- this page: hidden link
you see it will show two pages
if you choose Accessibility, which is only one item, the pagination still shows at the bottom. Clicking on it will bring back to the main page with all filters reset.
