Yes. The theme developer mentioned that it is caused by server issue. What do you think?

Because developer and I can’t reproduce the problem. The problem only happened in my users.

Yes I can upload from side.

I have asked all the users directly.
Some of them can, some of them cannot

It may be due to image size, hosting problem(I am not sure), php problem.

I have many users complaint of the same issue.

It shows spinning image when they upload, and it does not show upload success.

I have put many advertisement for users to sign up, it shows 0 users register when the photo is required.
When i remove it, till now around 15 users signed up.
Thus i believe many users cannot sign up due to image failure.

Please kindly advise
