File uploader error: File Not Found

By | March 29, 2017

When I try and upload images to my EE site (either from my file manager or from a file field in the channel entry form on the CP), I get a "Error: File Not Found" message. The file gets uploaded to my server, but the database doesn't have an entry for the upload.

Any thoughts on what is going on and/or how to debug the issue?
