When I click the navigation search icon on Home, pages or archives, nothing happens. On single posts, everything is fine (https://perfecthealthdiet.de).
I have already identified my caching plugin (Litespeed, as recommended by my hoster) as the cause of the problem: when I switch caching off, navigation search works as expected. But I don’t understand what to change — on my other blog https://dreiminutenei.de I’m using Litespeed with absolutely identical caching settings and everything works fine.
I understand this is not directly related to GPP, but maybe you can help anyway. Any idea where else I could look for the error?
Many thanks in advance,
