I see. I may try that, but am skittish about the possibility of messing up any theme customizations by deactivating it.

To answer your question, I’m taking about a situation where I have uploaded a photo into a post, using the “Add Media” button, and now I want to type in credit information for it. In many cases these are stock images that are purely decorative, so I don’t need/want captions–but do need to appropriately credit the artist.

Nothing appears at all when I try to save the credit — and so nothing appears in the HTML view. It simply doesn’t save, and the “credit” box remains blank.

I’ve done a lot of customizations to my theme, so I don’t want to try switching to a different one to test this. I’m surprised no one else has run across this problem before!

OK. Looking at the inspect area relevant to that photo, in console view I do see a lot of errors, but I have no idea how to interpret it, or if it’s relevant to this issue. (I’m using Chrome, on a Mac.)

I’m copying and pasting the text here:

Hmmm…I have no idea what that means. Can you clue me in?

Thanks for the quick reply. The WP version is 4.5.3. The theme is a customization of the WPZoom “Tribune” theme.

The credit info does not save at all when I hit “update”, and the little circle of doom adjacent to the credit box just keeps spinning. The inserted shortcode does not show up at all, in either the html or Visual views. Here’s the html for the photo:
<img class=”aligncenter wp-image-9802 size-full” src=”https://www.theopennotebook.com/wp-content/uploads/2016/03/shutterstock_182727164.jpg&#8221; alt=”shutterstock_182727164″ width=”1800″ height=”1523″ />

This problem ONLY occurs when I try to insert a credit on images with no caption, and I’ve tried it in several different posts.

Thanks…
