Configuring and Fixing VestaCP issues on CentOS dedicated server.

Hi, I have two issues regarding to creation of support email and MySQL db backup. 1. I created a support email successfully on vestacp, but I has been faced in following error message when opening webmail([login to view URL]). "CONFIGURATION ERROR [login to view URL] was not found. Please read the INSTALL instructions! " --------------------------------------------------------------- 2. Database Backup error on VestaCP. VestaCP sends following error mail to MY EMAIL every 5 minutes while working with backup. 'Can't connect to MySQL localhost ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)' Our website is interacting with db, I have an issue ONLY to make server backup on VestaCP. Note:Remember that It is very fatal to destroy db or server configuration because our site is in service. The works will be processed only via Teamviewer. Thank you.
