Cannot Upload To Assets

Hi

I cannot seem to be able to upload to assets via the page's popup window either by dragging & dropping or by selecting the file. Uploading directly to assets is working fine.

Getting this error message in Console..

/perch/core/assets/js/static/10.10.23f8a1427c17ade109a3.js:2

Uncaught Error: This file cant be queued because it has already been processed or was rejected.
