Yes, the Janrain plugin for WP. You say “have some issues” – can you elaborate? In my very limited testing, it seemed to work ok with SPF.
Any idea what could have caused the glitches on upgrade?
Also, on upgrade I notice there are 2 buttons where the 2nd upgrades the network. What does upgrade the network do – look for every site in a multisite install and update the tables? I recall seeing something in Trac about this functionality on very, very large networks when updating WP itself, and how some simple modifications can turn a process that could take 12 hours + to run into one that would run in several hours. If you’re not familiar with it, I can try to dig it up.
