Ultimate Member WP Help

I'm looking for some help with Ultimate Member plugin on our website.

Issues to be fixed:
- Image upload issue in the registration form (all images upload all ok but do not show up backend) https://www.elpromotions.co.uk/registration/
- Uploaded images are not displaying on the registration form, user profile page, or gallery section
- Change all registration from ALL CAPS to normal case (on both the frontend and backend)
- Update outdated template files - (see attached)

(The image upload issue in the registration form is not related to the outdated files however it needs to be fixed)

Thanks!
