Hello,
I am terribly sorry for the delay.
I have checked the site and it has A critical error has occurred on this site. Please check the site administration email for instructions. Do you have site backup? Did you install the site on clear installation?
Can i reinstall it all? I have changed the password. You can change in Cpanel back. If you permit to reinstall all, let me know what builder plugin do you prefer: Elementor or WP Bakery page builder?
Looking forward to your reply I will do in the highest priority.
Best Regards
