and i tried to set it to support/theme/storefront and get the message; already posted?

Looks like the main issue is that table where the image gallery is. If you can switch that to a standard WordPress gallery, it might clean it up. The table (currently) has a static width and thus will not display correctly on anything below 1200px wide.

Thanks i understand what you mean, but i did not change the table, before it was ok. Now I have no idea how to get a standard gallery table again??? any suggestions how to ?

i looked at this help: https://www.wpbeginner.com/beginners-guide/how-to-create-an-image-gallery-in-wordpress/ but under posts, as they state, i do not have galleries or whatever.
