Hello @robinstn thanks for getting in touch. I can see that you are facing a few different issues here so thanks for sharing all of these along with your site health.
This looks like it could be REST API related. I can see that you have the Stop User Enumeration plugin installed and active on your site which looks like it may interfere with the REST API if selected. Could I ask if you get the same errors and issues with Site Kit if you disable this plugin on your site?
If you still see the same issues could I also ask you to try our troubleshooting steps here and let me know how you get on with those. If you have any questions on the meantime then I will be happy to help with those.
Hi, I deactivated Stop User Enumeration plugin but that didn’t solve this issue. Can you share me the link of the troubleshooting steps?
Apologies, here are the troubleshooting steps. Let me know how you get on.
