How to enable timezone changing in account user page
Where do I find the setting to enable the user to change his or her timezone in the account page?
The Timezone option can be managed in your profile > account page. Just scroll down a bit you'll find it.
Please let us know have you used wpForo – User Custom Fields?
Just to clarify, have you tried to change the Location and Timezone form your account page as admin? Also, please try to check, can you change the other member's location.
Have you written any CSS code to hide those elements? Check it in Dashboard > Forums > Settings > Styles > "Custom CSS code" textarea.
