You are correct, a bit easier in linux where I can easily swap versions of gimp_gmic_qt in and out.
Version 2.9.7 works but 3.0.0 does not work.
I can get the plugin to show and sort-of run by changing line 35, the first 7 to some other number, 6 or 8 it is not bothered.
pdb.plug_in_gmic_qt(img, layer, 1, 0, '-fx_curves_interactive 7,0,1,7,0,0,'+pointLum+...etc
...but.. it makes a cartoon effect, not the same bright version as the original.
Question, Is there any reason why you need the old plugin ?
