Woocommerce photo reviews photos cannot be uploaded

Hi, when users try to leave reviews on my site, it will not let them upload photos. Whenever they try to upload a review with a photo, it gives them an error and doesn’t cause a review to be left. I have tried small and large photos, and none work, despite the plugin settings saying it is functional.

For any photos to be included in a review, they have to email them to me and then I need to upload them to the review. Please assist!

Regards,
Luke
