jQuery not defined at s2member-o.php

I added a Stripe Pro form to this page but get an error that jQuery is not defined. Regardless whether I run a caching plugin or not, the error persists.

Can you point me into the right direction for fixing this problem?

Thanks,
Jan

Hi,
From what I see on your page, the problem comes from the fact that s2Member-o.php is called before jQuery.js (jQuery framework files) …
Try to find what is delaying or defering the loading of jQuery.js in your configuration (cache, plugin, server configuration, etc …) and add an exclusion to this file.
Thanks.

I am working my way through debugging the individual components. So far it seems that either the Webarx security plugin or CloudFlare are causing the problems.

It turned out that CloudFlare’s “Rocket Loader” function caused the issue. Thanks for the suggestions, Brice!

Hi,
You’re welcome, happy that it is solved!
Thanks.
