Domain removed and new domain added, it can take up to 2 hours to start working. since removing a domain sometimes deletes the files associated with it, you can download a backup of your account before the removal at https://heliohost.org/backup
This account was suspended because you failed to provide a license for the paid software you were using. We can unsuspend this account after you provide proof that you have a valid license for the software.
In this case, you can use the Errordocument directive in .htaccess for each domain. for example:
# For 403 errors
Errordocument 403 /errors/403.html
# For 404 errors
Errordocument 404 /errors/404.html
Note that you can name the folders/error pages anything you want.
