Please look into this seriously. Our member facing site down after updating and was asked to return to the old version. My website does not use GP premium features, can I stop updating or delete GP Premium? I can use GP Premium is my new website.
did you update to GP Premium 1.11 ?
If so you can disable and delete the plugin and then re-install the GPP 1.10 version which you can download from Account > Downloads on this site.
