Hey, just a thought,

In case you already enabled guest user changes from salesforce, make sure that Master page is shared to the user of community profile.

Hi @Dave, Thanks for your reply. Yes in the user record I have added “Skuid Page Viewer” permissionset. Where in community I need to share the Master Page?

Hi

Open skuid page builder/composer for that master page, and click on more page actions dropdown and choose Share, then add to users needing it

Hope it helps
