Thank you, that worked! I tried to clear the log file, and do a few tests, but there are no errors appearing again, the error log stays clear.
One thing I noticed – since you are hiding the search settings, not using them whatsoever, I would recommend removing all of the taxonomy filters completely: https://i.imgur.com/kUBzodg.png
You can completely turn off the settings visibility as well here: https://i.imgur.com/Wo87w4g.png
