I sent a private message, and to respond specifically:
“By the way, it broke in more ways than I expected: today I sent someone to the membership site, expecting that the redirect would take her automatically to the sign-in page -but it didn’t. ”
Not sure what redirection you mean. When the user tries to view a restricted page and gets sent to the Membership Options page?
Yes, that’s it.
“I admit I didn’t de-activate every single plugin, nor did I test with a clean installation of WP (I tried but I’m a rookie when it comes to IT, and I couldn’t finish it without finding hurdles I couldn’t surmount). The theme hasn’t really changed. I did de-activate the one plugin that wasn’t there before S2Member “broke”. ”
I see. Well, to really rule out a conflict causing your problem, you’ll need to deactivate plugins and have the default theme… Since this is not always possible in a live site, that’s why it’s good to just install a clean WP in a separate folder to test and try to reproduce the problem.
I totally get that. Unfortunately I couldn’t set up the mirror WP installation by myself. Having said that, if it did work, then I might still be at a loss as to how to fix the current installation…
“This on top of the redirection problem with Paypal, and the fact that Google Buttons don’t work at all. ”
So you’ve integrated with PayPal and Google for payments? And are you using the s2Member shortcodes for their buttons?
Yes I am -the page is http://yogaparalaespalda.com/programa-holistico-no-mas-dolor-de-espalda-dl/
Thanks again!
