Hi there,

I have an email contact form on my site and CSM is installed.

My settings for the CSM are:

Enable ajax responses? NO
Bypass the message template entirely on successful actions? NO
Submission Error: set as -> template_group/template (works fine with all cases except this ticket’s)
General Error: set as -> template_group/template (works fine with all cases except this ticket’s)
Offline Message: set as -> template_group/template
Accessibility: No Change (...)
Custom Actions: none set, both stay on—Select—

When I send an email using the contact form, email goes (reaches the destination). However, when CSM is enabled, I am receiving the Internal Server Error response.

When I disable CSM, all activity is normal and standard EE success message is shown and then returns to the specified page after the set waiting time.

This started happening after I moved my development site to live. In development, I was using the SMTP of my private gmail account and emails were going OK followed by the success message.

At live site (nexcess), I am using PHP mail option of EE and started having this problem.

How could I solve this?
