I am having interesting issue with phpmyadmin using a single login.
Specs:
OS-X lion, Apache, php 5.3, phpMyAdmin-4.4.0-all-languages.zip, VPN, Firefox
I have a server that I use as a testing server that I connect to on a VPN from behind my firewall at home. When I do this I am either on my laptop or desktop depending what I am doing. I installed phpmyadmin and it seemed fine till I switched computers. After a fresh install I can login and all looks well but when I login from my other system I get the following error on my system "Fatal error: Cannot redeclare PMA_Bookmark_getParams() (previously declared in /path to root/phpMyAdmin/libraries/bookmark.lib.php:21) in /path to root/phpmyadmin/libraries/bookmark.lib.php on line 40". The interesting part is that I can another browser and it works fine on the computer that was having issues.
