Programming circles

I logged in to a supplier's website for work and saw this note:

Action Required ALL [website] Users:

Please review this link with the [website name] Changes and training NOW to prepare yourself for the changes.

I clicked on the link, got kicked out, and saw this message:

Please login to [website name]
You are not authorized to perform this operation.
This is NOT a password problem.

Hmmm, well, then what kind of problem is it? Guess I won't be training on the new changes anytime soon if I'm not authorized. Funny, seeing as how I'm an administrator.
