Hi Michael,
Thank you very much for the feedback!
Bug Related to the No Results Container & Auto-Search Function in Repeating Loop When Reaching Last Page of Search Results
I did actually encounter this issue during testing, and it should be patched. I tested this by creating an error in the results counter, and returning the incorrect number of results. Whenever no result is returned after 2 tries, it stops and removes the no-results button and loader.
Can you please make sure that all caches are cleared? This was implemented into the main script file, and that tends to be cached heavily by browsers.
