I think I may have found the cause.
As per this post here:
I assumed it would be working OK with Classic Press, but after rolling back to WP 4.9.8 then I could connect, so I think there may be an issue with Classic Press
I ant to use SEO Analysis.
I add my login email and password, but it just goes back to the "Connect your account form. I have ticked the acceptance box and I know it is the correct login because it is what I use here!
Same issue whether it's my username or email
Thanks
In rank Math I have some redirections of old deleted pages that I have redirected to 410.
But they show as 404 when you click on the URL, also they show up in 404 monitor.
However 410 redirects I have done manually in .htaccess show correctly as 410 Gone
Do you intend this plugin to be supported for the WP fork, Classicpress, which is becoming a popular alternative to Wordpress for people who dislike the recent changes to WP?
