Using WordPress Cloudflare Plugin v4.12.4

Correctly connected via API key. On load of plugin, Red bar flashes across bottom with “Bad Request” error and but I can access home/settings page. I get the same error if I click on any setting like purge cache.

Any help?

I also have the same problem and don’t know how to fix it. It seems like a lot of people have the same problem

I also get the same error and now im getting a 500 error.

im getting a 500 error

and this is after enabling the Cloudflare plugin on wordpress - and Apply Recommended Cloudflare Settings for WordPress

I’ve tried disabling and bypassing it but it doesn’t seem to be working?
Ive checked my hosting config and all that is still the same. but this error is not fixing it self.

any help or suggestions will be welcome?
