WordPress Database Error in Theme “Internet Market”

I’m using the WordPress Theme Internet Market (https://themes.wordpress.net/columns/3-columns/368/internet-market-10/) Even in the test run, the same error I have shows up. Does anyone know how to fix this error that shows up when trying to show the blogroll?

This is what it says:

WordPress database error: [You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ” at line 1]
SELECT cat_id, cat_name FROM

Help is appreciated.
