Hello Matt,

Sorry for the form error. The error that you're seeing appears to show a problem with your php.ini setting. You need to login to your php.ini file (local to your website installation) and then make sure that the setting shows "sendmail -i -t" not "sendmail -oi -t".

If you continue to have problems, also make sure that the modsec rules are turned off in the cPanel. Please try that first and then let us know if you require further assistance.

If you have any further questions or comments, please let us know.

Arnel C.
