Per tech support:
-------------------------
Sitebuilder storages all information (SQLite database, content) on the publishing server. The modules of eShop and Image Gallery was modified but site database was not. It is necessary to republish site. In any case we strongly recommend to create backup of publishing site before republish.
-------------------------
I republished the site and all is well. My eShop and Photo Gallery are back and were included in the published site. I can also modify them in once again in SB.
