The MAIN error_log seen at errors.html (the "Error Log" cpanel tool) is confusing, showing errors of other hosting accounts on the shared server.
It would help if somehow the customer could identify which of the many errors apply to his hosting.
One suggestion to do this is list the user's IP and username at the top of that page along with a message such as "Error messages with your IP XXX.XXX.XXX.XXX or username <user> are for your hosting account." Perhaps another disclaimer message could read "Due to the nature of shared hosting, there can be errors listed in the MAIN error_log to ignore because they are for other accounts that share this server."
