Thank you for this plugin. I believe it will work beautifully for us if I can resolve one issue.
I am trying to process transactions through Authorize.net AIM with a shared SSL certificate. When I submit the donation form, I see a message 'Processing', then a red error box that says 'You are not permitted to perform this action.'
I have not been able to locate the code where the 'Processing' message is generated, nor have I been able to determine the actual error. I have tried echoing payment transaction values in functions.php, but no values are displayed.
(1)Does the plugin work with shared SSL? If not, could you tell me which part of the code I could modify to make it work?
(2)If it is not an SSL problem, what would be the best way to identify the cause of the problem?
