Devtools failed to parse source map

I am hoping someone understands what is going on here.
I had site in staging, then siteground indicated that they are changing hosting. So i had to get out of staging. I went live a few days ago (without being finished in staging). THe site was showing pictures and maps prior to going live.
But in staging i was having problems with viewing pictures and maps (which i assumed was a problem cause by being in staging).
Anyway, now i am regoing through the whole setup again starting with core. I checked the google maps issue page and i seem to have had maps loaded(9000), but nothing since getting out iof staging. But no errors either. What i am trying to say is that it appears the maps is ok i think.
I checked the page on the google dev tools in chrome and i am getting the subjectline warning. There is also an issue about the autoptimise, so i deleted all the options to cache css. but same thing … still no maps load.
i cant find anything i support forum about this. Do you have any idea?(pictures also appear to be a problem)
