I checked out the latest from the Git repo and tried to use the Set Featured Image dialog to upload an image for a custom post type post.
The image uploaded sucessfully, and I can see it on the file system and in the Media Library. However, I was presented with this error in the right-hand side Uploading sidebar
Error application_delete.png An error occurred in the upload. Please try again later.
I think there are three problems here:
- The error is a false-negative
- The error message gives no technical details about what when wrong (and therefore, how to fix it)
- The error message implies that the error will fix itself if the user just waits a while
I think the error message should give specific details about the underling technical problem with the upload, so that the user knows how to fix it. It also should not imply that it will fix itself if the user just waits and tries again later.
