Getting TokenMismatchException in VerifyCsrfToken.php line 46: when uploading an image using Elfinder

Im using Laravel 5 with CKEditor and Elfinder to create a WYSIWYG editor in a CMS. Ive got the file browser up and running, but i cant get the file upload to work. I have the upload tab, but when I click Send to Server I get the following:

TokenMismatchException in VerifyCsrfToken.php line 46:

Any ideas why this is happening?
