Ultimate Member Profile Image upload

Hello,

I am using the Ultimate Member free plugin. Once a user has registered, their profile page is showing fine with a default photo. However, if they choose to edit their profile, specifically their profile image, it is not working. I would like to be able to use this feature.

It will allow the user to choose an image and select upload.

It then freezes at the end of the upload with a full green bar (see below).

I have checked in the WP-Content/Upload/UM folder and the image is being uploaded under “profile_photo_temp.jpeg”. However, it is getting stuck and not changing from this screen. It just sticks on the image above without being able to crop the image or select apply.

Do you have any suggestions on how I can correct this?

Is it to do with file permissions? File size limit seems okay and the image is loading as temporary. Any guidance appreciated. Thanks.
