'template usage', 'explain' clause in $debug

[Lionel]

I am attempting to do some optimization. After I placed $debug=1; in config.php (I also tried in global.php), when I click on explain, nothing displays (in config I get a blank page and in global it simply refreshes page). I uploaded a clean functions.php and a clean global.php. No luck. What else that 'explain' thing is dependent of so I could upload it? Or is there some other settings I should turn on?

Put the debug line in config.php and it should work.

it's just if you're using vb3.5 it must be $config['Misc']['debug'] = 1; instead.

I am using 3.07 and it does not work
