I opened the “user profile” option in addons. Profile page is in the default view of buddypress. How can I make it look the same as the appearance of AskBug theme?
It must be like this: https://i0.wp.com/anspress.io/wp-content/uploads/2017/02/askbug-update.jpg?w=640&ssl=1
Goto AnsPress options on your wordpress dashboard, click on Options and Add-ons, then turn on User Profile option so it turns from gray > green. That is all you need for your user profile to appear just as that of askbug theme. I hope this answers your question.
