Upload photo can click on apply

Hi,
Trying to test the membership on edit profile and adding a photo. But whatever I tried to it doesn’t work. I mean, when I upload and selected the photo, it gives me the 100% green bar, but the apply button not working. When I looked at the console it gives me this error.
GET https://www.domainsample.net/wp-content/uploads/ultimatemember/1/profile_photo_temp.jpg?1619040318479 404 (Not Found)

I have also tried all the steps here https://docs.ultimatemember.com/article/114-photo-uploads-not-working and contacted our server to enable the PHP features that were suggested but it still doesn’t work…

Any advice on how I can get it to work?

Thank you
