I finally narrowed down my issue with the Advanced Custom Field image upload problem I was having. (Essentially, uploading images through a custom field would throw a generic WP error: "An error occurred in the upload. Please try again later."
Finally, after hours of debugging I determined that when I disabled the Infinite Scroll plugin, the issue was resolved.
Has anyone else found a fix for this issue? I am running the latest version of everything:
- WP: 3.5.1
- ACF: 4.1.4
- Infinite Scroll: 2.6.2
Also, a colleague of mine has developed a completely separate site, using the same plugin combo - and has the exact same issue.
