Originally, BeansTag will check if there is any existing meta tags in the page which is going to be rendered. If exists, the BeansTag module will do nothing.

As requested by a BeansTag user, recently i have added a BeansTag settings page where you disable this checking.

 

If this option is checked. BeansTag will override the existing meta data.

Done =)

Reference: BeansTag – Override other metatag modules, possible?
