After a lot of hassle and additional coding we got WP E-Cpmmece plugin (Gold version with Members extension) working on our website that sells monthly subscription packages.
However today we discovered the option for PayPal Standard Payments (which we use for recurring payments) has vanished from the live and development site backends WordPress > Settings > Store > Payments tab.
Anyone got any ideas on this? We have contacted PayPal who say everything is well. No-one unauthorised has been in the backend and we have not installed or changed any other plugins or settings. Thanks in advance for any suggestions.
