This sounds like a plugin conflict.

Okay thanks, any ideas which ones?

Here is my list:

It’s difficult to say, because I don’t use many of these. Deactivating them all and then turning them on by one and testing is the only way to know for sure.

I’ve just tried this and I still get the error with JUST s2member activated and everything else off!

Does my shortcode look right?

I’m not an expert on shortcoes, but it looks OK to me. The only other thing I can think of is a theme conflict. Have you recently updated it?

Otherwise, I’d suggest you contact Pro support at s2member.com/contact

A few hours ago, my Pro form stopped working too. Not the identical same problem – but strange that there’s multiple issues with pro forms that previously worked that no longer do.

I’ll post my issue seperately, but wanted to flag as I’m also using Pro forms but for PayPal payments only.

Just solved this. It was the custom success URL that was creating the issue in the shortcake. I’ve got around it by removing the “success=LINK” from the shortcode. I had to recode some of the plugin to get a custom success URL link from the landing page back after being redirected by paypal back to the site.
