I created new form at V4 latest version, adding the payment option block, which I selected to hide, instead of leaving it out of form, for a free membership. This form is not going to be my default form. If I use the current default signup form, all works fine, but if I open the link to the custom signup form, I get the "internal error happened at script ". If I assign it as default, same error happens when link is activated. The log is: Exception HTML_QuickForm2_NotFoundException HTML_QuickForm2_Controller->getActionName [ library/pear/HTML/QuickForm2/Controller.php : 266 ] HTML_QuickForm2_Controller->run [ library/Am/Form/Signup.php : 125 ] Am_Form_Signup->run [ application/default/controllers/SignupController.php : 50 ] SignupController->indexAction [ library/Am/Controller.php : 139 ] The layout of form is only: Name, email, pasw, payment, agreement. When going back to the form editor, all bricks are aligned back to the right. Anyone has gone thru same problem and resolved it? Thanks in advance for any comment.
