I can't get to my email or cpanel, by puttin /cpanel or /webmail and the end of my url anymore. It takes me to some Forbidden page. Is there a way I can get to this?

Yes for webmail

http://yourdomain:2095
and
https://yourdomain:2096

For Cpanel:

http://yourdomain:2082
http://yourdomain:2083

For WHM:

http://yourdomain:2086
http://yourdomain:2087

My username and password for WHM doesn't seem to be working for it. What's WHM for and how can I access it?

WHM=Web Host Manager

You have this if you have a reseller account.

Ah, well that answers a few other questions. Thanks.
