Yeah, sorry if I sound patronizing. I never know how savvy the person I’m replying to is, so I usually resort to the simplest explanation possible.
Unfortunately it results in some completely useless answers…
So, when you click “Use as featured image” it changes to “Saving…” and just freezes? No errors, nothing?
In NextGen’s code, right after it does that, it uses the jquery post function to do the magic that actually sets the featured image.
Is there a possibility you have multiple versions of jquery?
Between plugins and themes, a jquery version or two can get included causing problems.
It would be hard for me to debug why it’s not working for you without actually getting a look at your setup.
Other random advice: Any other updates since it worked? Try disabling plugins etc. What changed two days ago ^_^?!?
If you want to get down and dirty with the code, I would be willing to point you towards the relevant NextGen files and code that should be setting the featured post.
Since you get the “saving…” that part works, but either the Jquery.post doesn’t work (because of multiple version of jquery) or the post never completes.
There is plenty of error handling code in there, the link should say “error” if something goes wrong, or it should exit out in some other way.
I actually just tested it (edited code to make it fail) and the error did show up in the box where the image should have been.
The post seems to be the issue, at least according to the info I have.
