500 error after enabling cloudfare plugin

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?
