Membership Pro Plugin is working perfectly on a live website except for one thing: When I go to ‘All members’ > ‘Subscription details’ I’m not able to save changes like ‘Expire Date’ made under ‘Manage subscriptions. Clicking the ‘save changes’ button will result in a 500 server error.
Url is like this: …/wp-admin/admin.php?page=membership2-add-member&user_id=367
Any idea how this is caused and how it can be solved?
I’m using version 126.96.36.199
Thanks in advance!
