You could add a function like this in your child theme’s function.php:
function mb_excerpt_more( $text ) {
return '';
}
which overrides the readmore function of the theme. Refer the following file for other hooks and overrides:

The latest MB theme is builtup from ground on HTML 5. IE7 and IE8 doesn’t have support for HTML 5. This could be the reason I guess. I am also suffering from the same thing.
