The initial problem was that images where correctly added to site posts, however, those images were invisible after the 4.5.1 update of the site. The 4.5.2 update had similar results. The images were in place, but simply invisible.
I have been told by more knowledgeable individuals at my company, that this effect happens for web sites (earlier referred to as pages) which have no security key.
Hello,
I reset the entire site, and used an older 4.4 wordpress template. Then re uploaded content. My web master tells me recent 4.5.1 and 4.5.2 updates cause images to disappear for pages without a security key.
Im now looking into a getting the security key, a little hesitant to ever update the site again.
