Troubles with my open id provider. How to debug ?

Question

I have my own openid provider on my website, with phpmyid. It worked flawlessly until now, but apparently now it's not working anymore. I am unable to login anywhere I tried. How can I debug what's going on, to understand where's the problem ?

I can add more details if required, but if I can figure it out by myself without having to paste stuff it would be better.

Answer 1

Without any details, all I can say is read the logs (if phpMyID provides any), and capture the browser redirects with something like TamperData to see if there's anything obviously wrong there.
