Recently I installed two plug-ins (Firewall) to protect the website to unknown threats, however since the changes the 'theme post list' (specifically people) is not showing correctly.
In Elementor it shows the correct version, but when I preview and update it changes completely. I have read other blogs and have deactivated and deleted both plug-ins. Deleted cache etc.
In addition: the only thing I have added to the website since the error is a SSL certificate. I contacted the host of the website and they said that the certificate has nothing to with changing the theme. How do I solve this?
