I keep getting the forbidden message when browsing or deleting mail form time to time, what is causing this? Forbidden You don't have permission to access /webmail/ on this server.
Check the apache error.log. maybe you have mod_evasive installed and the limits in its config are too low for roundcube.
you are right, I didn't realize I had it installed.. I made some changes to the settings sudo nano /etc/httpd/conf.d/mod_evasive.conf
