I keep getting kicked out of the system when I try to add a page through the sitemap in the dashboard. I'm led through all of the steps, and when I click the "add page" button, I'm automatically logged out of the system. Upon logging back in, no changes are saved.

I've tried various browsers (Firefox, Safari and Chrome) and keep running into the same problem.

One person in our office isn't having this trouble on his MacBook Pro, but two other MacBook Pros and an iMac (all computers are operating on 10.6.8) are having troubles. Our users all have the same permission settings...and the individual within the office that can add pages can use any login without difficulty on his computer.

Any help would be appreciated...
