Create a publication, but can not publish or attach photos

Hello Karen, this is the page I'm trying to post on

I change from "posting as" from my personal account to my business account. The photos never appear, and no button "Publish", no error, I waited a minute +,

can you explain "tab thru to the button"?

No, I have not tried mobile, my photos, etc. are all on my desk. One of the photos is 730KB, another 1.8MB and a 7.8MB.

I do not know if I block scripts, I have Ad Blocker, but I disable it for the FB.
