Help! Payments stopped being processed!

I activated script debug and get:

Uncaught ReferenceError: jQuery is not defined

The lines mentioned point to membership pro’s script. Help. Emergency. Lost every single sale this weekend.

OH no, I deactivated PMP and reactivated and now all of my pages are missing but I can see them in the back end. I’m freaking out.

Got the pages back. STill have JS errors on page. I deactivated all plugins and it is still not working.

OMG. I deleted PMP and reinstalled and now all of my settings ad pages are gone. OMG. OMG. OMG.

It’s been an all day event. This is horrible.
I have reinstalled the plugin but all settings are gone. I have done a db reset just for the plugin. The pages are back, but admin settings still empty. And idea how to get this fixed?

I have no idea if this is the cause but many errors on your site are about your SSL certificate. PayPal is not going to support the version of SSL that you’re running – starting in June 2015 (aka “now”). It’s possible that this is the cause of the problems.

(I know that doesn’t look like a PayPal link but it is.)

If this is the problem then it has nothing to do with PMPro.

It was a plugin.

What version of SSL do I need? I paid a lot for this one, set up through my hosting company.
