Getting Server Error 500 when trying to submit

I get a Server Error 500 when hitting the submit button on a form using the authorize.net add on.

This is what shows up in the PHP logs:

PHP Fatal error: Class 'JParameter' not found in C:\xampp\htdocs\administrator\components\com_chronoforms\form_actions\authorize_net\authorize_net.php on line 17

Any suggestions how to fix this?

Thanks!
Chris

Hi Chris,

I don't see JParameter on line 17 in the version of the action I have installed. It may be that you have an old version - IIRC Joomla! removed JParameter in Joomla! 3. If you need the updated version of the paid action please use the Contact Us menuy above to ask Max for the Joomla! 3 version.
