All of a sudden, I'm unable to add/remove files (using a vanilla file field) from channel entries. No dialog appears, no error in the page.

The console does show errors - but I'm not sure how to address them:

> Found third party scripts in <head> tag.
  Please use cp->add_to_foot() to add scripts. jQuery and the EE global will be moved down in a future release.

  • Did you update to EE 2.8 recently? What add-ons, specifically fieldtypes are you using? Mar 4, 2014 at 16:43
  • This is a 2.7.3 install. The only add-on I installed is Matrix, (in Matrix fields I'm not having any issues uploading files).

  • I'm having this identical issue (the third party message and add_to_foot, not the others) with my 2.7.3 install. In my instance, the vanilla upload field is in a matrix and is just showing {filedir_2}filename.jpg instead of the upload control.

I was able to solve this problem by comparing my current EE installation with a previous installation. The <head> of my 'admin.php' file was missing references to js files that my previous installation had:

<script type="text/javascript" src="http://www.example.com/themes/javascript/compressed/jquery/jquery.uniform.js"></script>

<script type="text/javascript" src="http://www.example.com/themes/javascript/compressed/jquery/jquery.dropkick-1.0.0.js"></script>

I made sure these files existed, added these references to admin.php, and uploads are working.
