Virtuemart 2, Joomla 2.5 SSL and mail problem

Hi, I had Virtuemart 2.0.6 and Joomla 2.5.6 working perfectly well with a custom payment plugin.

Now my hosting provider installed a SSL in the server and I'm having problems processing payments. It occasionally works on Safari, but not on Firefox, neither on Chrome.

On the final step of the check out I get an "Command Error" alert on the site.

Also, Virtuemart is not sending the invoice to the Administrator whenever a purchase is done.

the site worked fine, but there are 3 things that may be the problem

1- The SSL
2- The emails of the site are handled by Gmail and Google apps.
3- There was an old site in a different server, so I redirected the DNS to the new server with domain topotepuy.com, however, I decided to leave the store in the subdomain wp.topotepuy.com/tickets and installed the SSL in wp.topotepuy.com
