After enabling SSL, clients get redirected to wrong page after payment done.

Hey there guys, 1st post here.

The latest problem I've had is after enabling SSL on all pages, now clients get redirected from the payment platform back to the checkout page, and the items on the cart are not cleared. No purchase confirmation emails are sent to the clients, no purchase records on the backoffice. Just as if no transaction ever happened.

Not only that. Worst thing is, the payment transaction goes through. 

This could mean prestashop now never gets notified by the payment platform website when there was a successful transaction. (Or canceled for that matter; when transaction is canceled, user gets redirected to the purchase history page.)

When SSL is switched back to off, everything works fine. This didn't happen before enabling SSL. Also works fine if "SSL on all pages" is off.

Uninstalled the module, but when I tried to reinstall it, it wreaked havoc on my website. Can't enter the modules page anymore. Store front is inaccessible. I get an error I found out about after enabling debugging (see attached screenshot).

Tried to reach the payment module developer, but no response so far.

by the way, website address: www.cervezawinnipeg.cl/tienda

Would really appreciate if you could shed some light on this.

Thanks in advance.
