"global_cfg not found" is result of incorrect path to basic application folder (in almost all cases, except when it is really missing) or if application could not reach that folder (has no access), and this is alternative list where program will look if not found in original location.
If that (original) location is correct and accessible, then this list is useless, but it would not generate error.

I never said it must be this way, but only gave an example that I'm using, and never had problems with it.
