[Plugin: WP Stripe] Popup is grayed out, how do I fix this?

Same here. I went in and removed the ThickBox code (in wp-stripe/css/wp-stripe-thickbox.css) that dealt with the overlay and now the pop works sans overlay but something is wonky with the AJAX Modal and the “grayed out” feature.

For me the NextGen Gallery plugin had CSS for the same styles and was overwriting the styles from this plugin because unfortunately they use !important. I could manually modify the nextgen styles which would fix it. It has to do with the z-index level. Nextgen was changing it to be higher than the modal.
