I’ve been trying to install the demos desperately as there is always something missing while importing.
so I was installing the theme on subdomains then when it is now working I deactivate it and delete the subdomain then recreate a new one and reactivate the theme on it.
So after a couple of trials, I got the message “You have reached activation number limit.” despite deactivating the theme on the previous subdomain and deleting the subdomain .
