I noticed the following issues on both of my ISPConfig 2.2.9 servers. When an admin account is created for a site, the login does not work. An error "ERROR 101: wrong username or password." is given. When that site admin user account is deleted and you try to create a new admin account, an error is given that an admin user already exists for the site, but no site admin account is listed.
Did you try to login with the web#nr#_#name# that you created for the domain (in the ISP Site part) as admin, or the Login Data name and password that you have set in the Clients part? Did you empty the Recycle Bin?
Ah yes, Recycle Bin. Ok, so now I can create another admin user. About logging in to the control panel for site admin, I tried with both web3_admin and domainname_admin for the username. Neither work.
Perhaps I am misunderstanding, and its only the "Login Data name and password that you have set in the Clients part" that can login to ispconfig control panel.
