"exceeded the maximum file size" error even when uploading small files This error in my Drupal 7 site happens when I try to upload an image through image_field field. This is the error:


  An unrecoverable error occurred. The uploaded file likely exceeded
  the maximum file size (64 MB) that this server supports.




Although I am trying to upload a small 5KB photo, this problem exists. I know this is kind of common problem, but can't understand why this happens for as small images as 5KB!

How I can fix this? At first I thought this issue may have been temporary and does appear to have resolved itself this morning but again it happens.
I found a workaround, as this is a tricky one to nail down.

Don't hit the "Upload" button at all.  Just hit the "Next" button directly.  If that works, you ran into the same problem I did.
