API's keep breaking down

These are my API. They stop working and cause major errors not long after i restart my API console. I'm hoping one of you can tell me why one or more of my API keeps causing crashing errors? I've installed these directly from the list in roll20 and havn't edited them in any way.  My list of mods: Concentration mod Combat tracker Status info Token mod Monsterhitdice and statsmod are disabled.

Concentration Mod, Status Mod and Combat Tracker are very old, if they are the versions by Robin Kuiper. Combat Master can handle those functions. Or Condefinitions if you want something simpler. I am not familiar with Statsmod. Tokenmod and MonsterHitDice are pretty bulletproof.
