Hi Martinko,
Relax as these “errors” could not cause any problems to your site.
1) This theme doesn’t need fixed content width parameters. However, you can add this line in functions.php file of the theme to get rid of the “error”.
2) Widget Control is not our product although we are using it in our themes. Thus we modified this plugin a lot. The lack of this function don’t have any impacts on site functioning.
Regards
Milos
