We have some users that have bought the Covert Store Builder theme and/or associated plugins here at Wealthy Affiliate. When you buy a theme (that is developed by a third part company), and that is not part of the Wordpress.org theme set, you are taking a chance.
In this case, this theme is NOT ALLOWED here at WA because it makes poor use of server resources and it creates many vulnerability to the quality of your website. I would recommend that if you are using this theme, that you please remove it immediately as we are going to be disabling all domains using this theme.
Also, be weary of buying any plugin or theme from a GURU or an Internet Marketing company. More often than not these are created by folks that "outsource" these themes or plugins and don't have a good grasp of technology, which is the case with the Covert Store Builder plugin.
Thanks.
