What exactly is your question/issue?
The issue is that the text does not wrap around images like it’s supposed to in TinyMCE in the case when no caption is specified. I’m wondering if there is some workaround for this problem. Also, I would like to see this fixed.
Does it act this way when you use the default theme?
No, this doesn’t happen with the default theme.
Then, it appears that this could be a theme issue. What theme are you using?
I think you’re right (that it is a theme issue). I’m using a custom theme which is based on the Kubrick theme (which is now retired).
Yeah, anything that is retired is not supported so you may need to choose a more current theme or have a developer customize it to work with the current version of WordPress.
I was able to fix the problem myself (it was a function to strip styles that I had added to functions.php). Thanks for your help.
