[2.4] Nothing is displayed by my browser when I try to run phpMyAdmin, what can I do?
Try to set the $cfg['OBGZip'] directive to FALSE in the phpMyAdmin configuration file. It helps sometime.
Also have a look at your PHP version number: if it contains "4.0b..." it means you're running a beta version of PHP. That's not a so good idea, please upgrade to a plain revision.
