I created a basic template page, adding:
<?php echo wp_stripe_form(); ?>
The layout is messed up and css tweaks don't really resolve it. If I use the shortcode instead, it doesn't open up in thickbox. It changes the url and loads outside of my theme. In this case, the layout looks perfect. I don't know what else to do to resolve either issue.
In this example, I have the shortcode in the template page I created so that you could see both issues.
I really want to use this plugin. Thanks for your help!
