I believed that it was the embed codes that are displayed on the upload user interface, that's why I mentioned the redirect on single upload. From the images the issue is something else, so I don't know which is the specific issue or this is a two-issue thing (for which please, keep it to one issue per topic and you can post multiple topics, but please keep it in one subject each time).Following an image upload it goes directly to the images page bypassing the embed code window entirely.
CHV\isShowEmbedContent()to show/hide that content. You should check that all files are updated and that your custom theme changes (if any) are updated.
On the image page, under the "Embed Codes" tabs nothing is displaying when it's opened. The "About" tab and "Full Info" tabs display fine.
The images I attached show what's going on.
