Really nice looking site. Can you make this change in your framework/functions/thumbnail-functions.php file at around line 30 –
/* Return false to disable image info on hover */
function mo_show_image_info($context) {
if ($context == 'portfolio') {
$enable_hover = mo_get_theme_option('mo_disable_portfolio_hover') ? false : true;
return $enable_hover;
}
return ($context == 'archive' || $context == 'starter');
}
and see if that helps? I will have this change in the upcoming update and hence you do not have to repeat this change again if you update the theme.
