After registration, membership should take you to Paypal. It doesn;t!

Hi

This system was working fine. Did updates of plugins. And now when someone clicks join, they get to the registration page (good).

Then they click next which takes them to the payment page (paypal). It doesn't (this is bad).

It leaves us with the waiting symbol. And stays there (this is very bad).

Then sometimes a message comes up re This page has a redirect loop. I have cleared the cache. It still happens.

Can you help? I've missed out on 2 membership sales today.

I have granted support access in case it is needed.

Speedy help appreciated.

Thanks

Graham
