After 14 successive iterations in EA, and equally successful Chrome previews, all 14 were inaccessible to the error above.
I don't know why, I don't know the repercussions, but the following allowed me to load the file into EA again:
In the _edge.js file - many fonts. One I do not even recognize.
I deleted all highlighted in blue.
If you have more info on possible effects, please contribute below.
Thank You g.bollmann, that worked. I removed unused fonts and it also looked like some were listed twice.
Thanx.. you made my day
