i guess answer better no answer, here mine:

i thought component cannot work on both j1.5 , j3.0 simultaneously. see separate installer/packages j1.5 , j3.0 versions separate downloads component.

anyways, think you'll need debug php hand, line line. search site error message get, , narrow down comes , narrow down when happens when error.
