@paoltaia @wpdev10 Yeah reCAPTCHA was enabled in WordFence settings, while I think it was also enabled in the UsersWP settings: https://i.imgur.com/Uyz0Z1W.png
The login works now after disabling it, thank you all for the help! I’ll be more careful with these security plugins, so they don’t overlap each other.
Yes, sure. I have created one now.
Hello Patrik, I tried to disabled the caching plugin and also tried with a cleared cache, but it still kept loading. I then tried to exclude /wp-admin/admin-ajax.php and also tried after clearing the cache, but it didn’t fix t he issue.
