I have both ACF and the “Infinite Scroll” plugins enabled on my site. It seems that I can’t upload images through the admin any more (I could until not too long ago) unless I disable the Infinite Scroll plugin. I’ve seen people have run into the same problem:

The error I get, immediately after uploading, is “An error occurred in the upload. Please try again later.”
Are you aware of this problem? Can you offer any solution other than turning off the “Infinite Scroll” plugin?
note that I’m trying to upload an image through a custom image field in the post edit page. Uploading a file to the media library, not through ACF, works perfectly.
I have the exact same problem with the custom image field (ACF v4.3.8) on the posts edit page and the Infinite Scroll plugin (v2.6.2 by Beaver6813, dirkhaim, Paul Irish..) on WP 3.9.1.
Disabling the Infinite Scroll plugin resumes normal operation to the custom image field.
