Membership Auto Renew

Hi Guys, sorry to bump a threat but I posted an update four days ago and have not yet had a reply. Here's the original. https://premium.wpmudev.org/forums/topic/memberships-auto-renewing#post-379325

For some reason the memberships are still not renewing. They were switched for some reason a while back but we've switched them back to the paypal express gateway.

I've since set up a dummy £0.01 membership to renew on a daily basis and this seems to work fine.

Is the problem possibly that the memberships have been messed about with a bit and have therefore switched off renewing?

Please could you advise.

Thanks
