Q: My Author Page redirect to HomePage or shop page when i active Woo Commerce Plugin?
Ans: Please Make sure your New User role set to Contributor Not Customer.
1- Come to WordPress Dashboard --> Settings --> General --> New User Default Role --> Select Contributor. Save Settings.
If some user's already signup with Customer role. Then.
Come to WordPress Dashboard --> All User --> Edit user one by one any change user role to Contributor .
That's All
Thanks
