User profile link issue

Our website in sub-folder called “LMAM” when we try to access the user profile the url redirect to “lmam” so the page displayed with 404 error.

Is there any way to accept capital letters also.

I think the um_user_profile_url(); function converting the capital letters to small letters.

Ex : https://www.mediafactoryintl.com/lmam/user/9516/ instead of https://www.mediafactoryintl.com/LMAM/user/9516/
