Ok,

For some unknown reason I cant access WHM main page, says password is wrong................... BUT!

I can access root via SSH using the same username and password?

SO....
1) How do I reset my WHM main password.
2) Can it be done from SSH root.
3) Looks like I've lost the .htpasswd file so how do I stick it back and were is it.

Thanks

I am not sure about this but I guess the WHM get the root password from the system shadow file.

Try restarting the WHM and see if you can login.

Nope, did not work.

Solved!

It was me using the wrong username

Owe well, at least its working.
