While testing websitepanel out I was trying to add FTP and MySQL to the hosting plan so customers would be able to use it, but I didn’t get it to work. So I tried to delete the current user and make the same one again with the same domain(I have one domain to test with) and now when I try to add a website I get an error saying the request failed to complete.
From the account home, under the account menu, can you post what the audit log is coughing up? I’ve found that tends to tell you what’s going on in cases like this. I’ve seen this happen before if the domain wasn’t properly detached. The audit log should tell you what’s going on. I hope this helps!
