I've been working on creating a custom master page for a customer and it is working successfully on my dev server. However when I try to added it to the customer's server and change master pages it always appears as Seattle.

Both the sites are Team Site templates with publishing features enabled on the Site Collection and Site level.

It appears as if the customers site is Stuck in Seattle, when I try changing it to the OOTB Oslo page it still remains as Seattle. I think there is an issue with their site.

Has anyone heard of this issue before, if so how do I fix it so it will use the custom master page?

Note: Yes I have upload the custom Master page correctly and I can see it on _layouts/15/ChangeSiteMasterPage.aspx

Update: Change Site Master Page

  • what's the template type (Publishing, team site ....etc) of your customer site? Sep 5, 2017 at 13:58
  • if you have uploaded the master page, I think you need to go to master page gallery and edit the properties and then change the content type to master page for it to appear under the master pages dropdown, otherwise you'll just see the ootb master pages, as seattle Sep 5, 2017 at 14:28
  • @M.Qassas I'm using a Team Site Template with publishing features turned on.

  • @TiagoDuarte The master page and all the scripts and styling have been uploaded and published and I can see the master page on _layouts/15/ChangeSiteMasterPage.aspx

  • so you can see it, you can apply it, you just don't see the branding? if that is the case, you must have the references wrong. check your browser console for 404s Sep 5, 2017 at 14:44

Check what type of page you are using in the production. If it's Web part pages, for example, then you need to apply "System Master Page" instead of "Site Master Page":
