On crop screen after clicking 'Crop!' buttons grey out

Hi,

I can upload an image via the ACF upload image with your plugin added on.

I have it forced to crop so when the image has successfully loaded and selected, the ‘Crop’ modal appears. The image area appears with the marching ants line as specified and the Preview area is there too.

I can drag the crop area, resize it etc with no problem but as soon as I click the ‘crop!’ button both that button and the ‘cancel’ button grey out and the image just sits there doing nothing.

I can click the ‘cancel’ button even though it is very faint but the cropping action just never completes.

I’m using ACF 4.4.5 and your add-on version 1.4.7 with WordPress 4.4

EDIT: I have tried completely uninstalling and removing your plugin and re-installing it with no joy.

EDIT 2: Sorry, I forgot to post the Console log. This is the only error I get:

https://mydomain.co.uk/wp-admin/load-scripts.php?c=1&load%5B%5D=jquery-core,jquery-migrate,utils,plupload,plupload-html5,plupload-flash,plupload-silverlight,plupload-html4,json2,imgareaselect&ver=4.4:3 Uncaught Error: Syntax error, unrecognized expression: #post=1098&action=edit

where 1098 is the ID of the post containing the image in question.

When creating a new post, the error changes to https://mydomain.co.uk/wp-admin/post-new.php instead of #post=1098&action=edit

Thanks.
