Which _main.php did you change? The one in skins/yourskin folder (for all installations), or the one in b2evocore (for pre-1.6 installations) or evocore (for 1.6 installations) or ???????? (for CVS version installations) folder?
Undo the changes bit by bit until you find which portion is killing your blog OR show us the parts you changed so we can try to help. Only the parts you changed please! Most of us know what the _main.php file looks like ;)
Oh and the version of b2evolution you're running will help.
