I'm facing a perplexing issue with making my changes from a master page reflect on the front-end.

Strangely, if I enable my new master page on System Master Page it works, however when I enable it on Site Master Page changes only appear on the SP 404 page, not any other pages. Clearly, I'm missing something.

I am Using SharePoint Designer 2013. Also, I have Checked In and Published the changes.

I have read through most other duplicates relating to this question and I have tried all proposed answers and am now seeking further guidance.

My SP site is a Publishing Site, with a Welcome Page set.


  • How did you identified that it is applied only on 404 Page? you manually accessed the page or you accessed your site and you landed on 404 page? – Litt Spector Sep 12 '19 at 11:07
  • Hi, I purposely looked at different pages to check - to my surprise finding the Master Page working on only that. – David.J Sep 12 '19 at 11:24
  • So the Home Page of your site has the default Master Page. and you are not getting any error? – Litt Spector Sep 12 '19 at 11:26
  • It appears so, I've set the Master Page within Site Master Page Settings - am I missing something obvious?! – David.J Sep 12 '19 at 11:27
  • Could not understand your last comment. Can you add the screen shots so we can get some more details. – Litt Spector Sep 12 '19 at 11:35
