Not able to access MySQL, not via Virtualmin or SSH. Tried everything.

Using Ubuntu WordPress on 14.04.

I installed Virtualmin and it says ‘‘MySQL does not appear to be installed and running on your system, or has not yet been set up properly in Webmin’s MySQL Database module. If your system does not use MySQL, it should be disabled in Virtualmin’s module configuration page’’.

**When I go to the MySQL Database module, it does not let me log in with any user and password combinations, I’ve changed them from the module’s configuration, from the system’s configuration, I’ve tried everything via SSH, yet it does still not let me log in and gives the following error: ** Login failed : Incorrect administration username or password

**and the error via SSH is: **ERROR 1045 (28000): Access denied for user ‘root’@‘localhost’ (using password: NO)

Doesn’t matter if I try a password or not, the outcome is the same.

I’ve literally tried everything I could find on the internet about this issue and nothing seems to fix my problem. Help very much needed.

Does anyone have any ideas? Thank you in advance.
