If I disabled xcore plugin things were ok.
I spent 2 hours figuring it out. In the end I deleted the Static block I was building and now everything works ok.
But I build a new static block and now I have problems again. I figured out why.
When I put a long google maps link, this one

inside the link field

everthing crashes and I have to delete everything. Even if I remove the linkt nothing works. I have to build a new footer
