Many Thesis users have had small complaint as there is no elegant way to remove the thesis attribution link from the footer which they are allowed to if they have the developer’s edition of the Thesis theme for WordPress. Thesis relies on the WordPress hook system and comes with its own many hooks, which allows unlimited potential for customizing Thesis theme. I think that there should have been an option under WordPress Admin to remove this attribution. However, Here I give you a one line of code which will do the magic for you.
Open you custom_functions.php and paste the following line of code:
Refresh your browser and Voila Thesis attribution is gone. As such you can also remove other html in a similar way. See the entire hook reference at the Thesis theme’s blog.
