got to install DT Register with no problems in Joomla 1.5.6. Authorize.net works fine. But not the email functions. No emails out. Created a ticket item on Sunday, but no response.
Global settings from Joomla I changed \"mailer\" segment to the prefer way of dealing with mail in my server \"send mail\". This is a simple place to troubleshoot similar \"email\" functions. IT will be great to make it part of some basic troubleshoot instructions as well. Keep up the good work by improving the support.
