Server Error when uploading Background image

[+A. Schilling]

When I try to upload Background images to my hides, I get this error. 
I use chrome and IE
It has been an issue for 6 months (or more)
It is every image and every cache hide

The image is not too large and is in the correct format.

I hope for some ideas to fix this problem

Kind regards
Anne

I've tried to update the background on two different caches of mine, and they won't update. I'm not getting any error message, but the image stays the same. Perhaps this problem is connected? The file sizes are under the 5mb limit.

I discovered that apart from the 5 mb limit the image also need to be app. 500/600 px or smaller. 
By amending the dimensions the picture was uploaded without error.

It seems like it would be helpful for the cache editing page to mention that.

Unfortunately, that doesn't seem to resolve my problem.

I am having the same exact problem and will try to make the file smaller, but it clearly states that they will resize the photo after it's uploaded. It seems to be an internal problem. Thank you for posting that you were having a problem with this feature so now I know it's not something I am doing incorrectly. Happy caching!
