When I go to "Password Protect Directories" in cPanel, I get an error. I couldn't find anything on google about it - but it seems that it's adding an extra / before public_html. Any ideas? I already checked httpd.conf and couldn't find a // anywhere.

Allow access only to authorized users
Please select the folder you wish to protect by clicking on its name.
Open a folder by clicking on its icon.
Internal Error, can't find that folder [/usr/local/apache/htdocs//public_html/]

This same error I found on google here:
