Not much of a clue or debug info ... but ...
Login as admin level user.
Use Site Admin Menu search box ...
search for 'cache' -
Purge all caches
Then search again for 'tour'.
Turn Tours OFF and let's see what happens.
That theme is sure doing a lot of advertising for itself on current site config. What if you changed themes?

Unfortunately, the initial error simply states that the response from the server includes something incorrect - it doesn't contain enough information to figure out what is incorrect.
What you will need to do is to look through the items found in the "network" tab of your browser's developer tools, in order to locate the response with the badly formatted content (there is a good chance that this contains an obvious error message).
If you post a screenshot of the "network" tab, then someone might be able to guide you as to which of the responses are the most likely to need further investigation.
Hi Fran,
It might happen to lots of different users on your Moodle site, but that still doesn't help to diagnose what is actually going wrong.
The error basically means: "there is something wrong in the response from the server"
To diagnose what that "something wrong" is, you would need to look at the content of the response and figure out why it is wrong. That can only be done by looking at the raw responses as contained in the "network" tab of your browser's developer tools.
