log in as admin, then get booted

Hello - I can log in to advanced guestbook 2.2 as administrator but when I click any topic, I get bounced back to the admin log in screen. I have used reset.php and the same thing happens with new log in. We have had some strange entries to our guestbook lately http://www.newcityfellowship.com/guestbook/index.php
and I am anxious to get my admin privledges back.
Thank you,
Linda Gutherie

Do you have phpMyAdmin?

thanks for the reply
no, I do not have phpMyAdmin

So your host doesn't supply cPanel then? Guess I will have to write a small script for you to upload so I can see what fields you have in the auth table. Did you do anything to make this problem happen or did it just begin?

well, yes, sorry - I do have cpanel and phpMyAdmin 2.6.3 pl1 - I have never used it, though - will you tell me what to do with it for this problem?

also - it just happened. I haven't logged in as admin for several months, then when I tried, got booted out after getting to the admin selections screen.

I have ftp access to the files and know how to edit them, if that helps.

I'd need you to go into phpMyAdmin. Select your database if needed then select book_auth from th elist on the left. You will get a structure list on the right. I need to now the field type of last_visit.

You might also want to update your GB from version 2.2

field type is "timestamp"
Should I go ahead and upgrade or try to solve this problem first?

upgrading might be a solution.
