I have been trying to get FirePHP to work for an hour now. I have the latest firebug installed and it works fine. I also installed the FirePHP addon. Then I downloaded the library files and included them in my php file. I am sure that they are being included. Now I started FirePHP with the ob_start(); statement. Then I tried logging something with fb('Log message', FirePHP::LOG); but nothing showed up on the console. I have tried looking in the Net Panel, The Console window, had All checked, tried using the OOP method, etc. but nothing is working. I can see headers being sent just fine but I cannot see any logged messages. What gives?
I have had the same problem a number of times. One of the following 'fixes' worked for me in the past.
