I have just installed phpmyadmin, but whenever I log in the screen 'Cannot start session without errors...' appears.
I can't find anything in the browser errors log or the Apache error log. Is there anywhere else I should look? It mentions a PHP log but I can't find such a thing anywhere.
As a (possibly) secondary issue, the login page is warning about being unable to load the mcrypt extension; I have the mycrypt installed (sudo apt-get ...).
The machine is running MySQL 5.1 on Ubuntu 10.4
