I also submitted to your plugin website support forum as I did not know which forum was more actively monitored.
I'm using Registration Magic 3.1.1 in conjunction with Gravity Forms and Gravity PDF to create PDF documents using user registration metadata. Everything was working great until I updated to 3.1.1 and then I began getting white screens on form submission. Form submission retus links to PDF files. The following error was generated on form submission.
"Catchable fatal error: Object of class mPDF could not be converted to string in /var/www/www.mywebsite.com/wp-content/plugins/custom-registration-form-builder-with-submission-manager/exteal/PFBC/Form.php on line 31"
Disabling Registration Magic results in proper form submission and no error.
I have not upgraded to 3.1.2 as I'm more inclined to roll back to previous working plugin you released.
Any help and suggestions appreciated. My ecommerce site has come to a screeching halt :(
By the way, I was loving your plugin otherwise.
Thanks.
