After upgrading to Kirby 4 I have a problem with the Kirby3-Instagram Plugin by @genxbe:

Your fix works.
But you need to check line 140 & 153. I guess you tried to replace all "DS", so "fields" become "fielDIRECTORY_SEPARATOR" which might cause the follow-up error that you get.

Thanks, I fixed that in the last commit.
