in rules and policies of this wiki is written:

"Another User's Page Editing another user's profile is considered impolite and should not be done without their permission. Changing spellings on their user page should not be done as the user may want it that way, and material should not be added or removed if you think it will look better, for the same reason. Exceptions include, but are not limited to: Correcting vandalism, To remove or fix a link/template. Fixing coding mistakes. "

so i think that fixing error is legal
