1.5.0 no grid or colored rows are shown

updated to 1.5.0. i open my file, but there´s no grid shown as before.
also no colored rows. in preferences design view it is activated

also this message is shown

The highlights don’t show on a remote site with http. It will work with https and on localhost. We are working on a solution for this.

thanks - switching back to local brings back the grid.
