ok, i should have at least tried to troubleshoot this on my own first SMH
the offending line in my stylesheet was:
this was a theme another gracious user shared that i tweaked to hell for my own use. I never touched that block of code and actually have no idea what it does or is supposed to do. but i've been using it for a while with no issue until maybe the last build or the one prior.
i'll just comment it out and go on my merry way, but maybe it is a bug? i dunno. lol
