Thanks Jason
Could making the Mhash change keep the transaction from being transferred to Auth.net?
If you go through the entire order process, it cannot connect to Auth.net - getting 103 error. If this is solved, we can go live with new site.
Also, though the phpinfo.php page now on the site (friendsofjeffersonbarracks.com/phpinfo.php) shows that hash is enabled and supports the MD5 referenced in the code, in talking with GoDaddy they say it is not enabled on this server.
Further when attempting to connect to the database on this server running 5.4 php (now using cpanel admin) - one uses "localhost" database name, user name, password - but it cannot connect. It is now running off my server database running 5.2 php.
Any suggestions for hosting services that might not have these issues?
thanks again
Greg
