Haven Theme slider not uploading images

Hey all,

Got a rather odd problem with a slider for the Haven theme. Not sure what happened, but after updating WordPress the banner disappeared and displayed this error message “Gallery you selected as a Slider Gallery in Home page settings contains no slides, make sure to upload at least one image for selected gallery.”

Seemed fairly straight forward, reset the gallery designated to the homepage slider and upload the photos again. however WordPress wont let me upload the photos. It will let me select a photo to upload, but once I press ok, nothing happens, closes the file select box and that’s it.

I check what was going on using chromes inspector while in the WordPress dashboard and it seemed to be a Javascript function in the Haven theme wasn’t working correctly. But I’m no Javascript guru so I wouldn’t know where to begin. But my guess is something with the theme has gone wrong. I tried switching to a different theme and then back, but to no avail.
