First off, great little plugin. It works fine for me out of the box.
Unfortunately I need to use a custom template to achieve my goal. When I copy the emailandnameform.php and rename it to ssd-emailandnameform.php and save it in the root of my active theme I get an Internal Server Error AND an additional 404 Error on the page where I placed the shortcode.
I must note that I am dynamically placing the shortcode into all members of a specific custom post type by using a custom field. Still, this works fine for me when not trying to use a template copy.
How can I troubleshoot this? Is this a problem you have heard of before? Got any suggestions I can try?
Thank you in advance for any help!
