Last resort debugging

When all else fails, I use The Scientific Method:

1. comment out half the code
2. see if I still get the bug
3. if no then uncomment half the commented-out code and go to step 2
4. if yes then comment out half the un-commented-out code and go to step 2

It’s fairly rare I need to do this in php, but currently hacking in vbscript which I don’t know at all …
