Hello Mikko,
thanks for your fast answer.
Query Monitor shows no Errors or warnings or slow querys.
When I use another Theme it also finds nothing … But it also shows no Content.
I Think it is because of the way the content is stored.
But in another way the indexer is able to find every single word in the “stopword” tab, which is really strange …
There is a big beTheme community “https://forum.muffingroup.com/betheme/”, I also aksed them if there are an changes regarding the wp-search. The answer is they haven’t changed anything regarding the the wordpress search.
