Hi@rv_ng#89280
It seems your website url is wrong or it is down i cannot access it, anyway if you want to override bootstrap limit for screen resolutions you can work with less file, specifically this one /templates/ja_directory/less/variables.less and change various settings as showed below, after you changed them you should click again on compile less to css button.
