We just had a member upgrade their site, but then couldn't access their dashboard, instead being presented with the option to select a "Supporter" plan (That's how we brand it), which they already paid for.
I was able to get their user credentials in our chat room at the time. So I logged in as them and confirmed that they were NOT being redirected to their dashboard, even though they had already paid.
As a temp. fix, I manually extended the Supporter status, which allowed the user to access their dashboard. But this shouldn't happen.
Checking our PayPal account, there is no IPN history for the transaction. And yes, IPNs are working fine for this domain and PayPal account.
The user created the blog and upgraded it using the Supporter framework
in 2009. Their attempt to modify the site's status apparently failed under the new framework.
I fear this is going to start happening for all our sites!
What other information do you need from me to determine what happened and ensure problems don't persist for our other 100+ Supporter sites?
