I have a masterpage called 'MYmaster.master" that has been deployed through a feature. It is in "_catalogs/masterpage/". At some point however, the page was edited manually, and redeploying and deactivating/activating the feature does not update it. My question is: How do I "reset" the page to match the one from the feature? This is at the root level and all other subsites inherit from it.

Hi, In site collection, go to Site Settings. Now User Look and Feel go to Master Page. Now select a master page and check box which has following text ahead: Reset all subsites to inherit this site master page setting I wish you every success in your important work. Best regards, David Hu
