Hello. I’ve installed ClassicPress through the Softaculous Installer through my Cpanel (on Namecheap.com). It prompted me to create a username and password. Done. However, when I try to access my admin page, this is what I get:
The general steps for setting up a new ClassicPress site are something like this:
Buy the domain name
Buy a hosting account and set up ClassicPress on it (it sounds like you’ve done this part)
Make sure the DNS is configured correctly so that when someone visits your domain name, they get directed to your hosting account behind the scenes
Specific instructions for finishing your site setup vary depending on your web host. I suggest getting in touch with Namecheap support and they can help you further.
