With the migration from Plesk to cPanel coming starting today, I have had to change some usernames in the system to be able to fix a configuration problem with the cPanel.
If you notice your username does not work any longer, try placing the numbers 16 behind your old username or open a ticket and I will assist you ASAP!
Thanks for your understanding,
