At the moment your userpage is protected because over 40% of your edits are on your userpage. This is shown in the userpage policy. To get your page unlocked you must make your user page namespace edit count go below 40%. You can view your edit count here.
UPDATE: You have less than 40%! Ask an admin to unlock your userpage and they will unlock it for you!
I hope I helped!
