UPS! I asked bluehost.com, (where I have webhosting) to delete two subdomains because cPanel errors occurred and it is impossible for me to remove them. In response to my request, an administrator (Brett / Technical Support Specialist Level 2) felt that it would be better (without being asked) to delete all my domains and their domains. Gooooddd! I'd better get on my feet and leave things like that.
For the moment I managed to restart stealthsettings.com, but under the domains they have to wait a few minutes.
so… smf. brb
