I got very simple task to make custom layout in SharePoint 2013. Nothing fancy: change navigation, add homepage etc.
I couldn't find a one and the best way how to create own master page. I have tried to modify existing master pages, so they could work with Composed Looks, but I got problems understanding, how css file is created. So I left this approach and tried to follow Benjamin's Niaulin article. And I got at least 3 problems.
First of all, when I go to a Design Manager, I have little different list:
The "Name" column is blank, but when hovering the cursor over icon, I got name displayed. Also, there is no field "Status" for conversion. Probably I'm on the wrong level (this is Design Manager for site level), but I'm not sure.
I accidentally discovered, that when I click "About me" on top navigation and then on a small cog, there is no "Site settings". But after that, I can click on "Site contents" and when I'm here, there are "Site settings" under the cog. This is very strange for me, I don't know what exactly I'm doing. And when I'm on this site settings and go to Design Manager, I have exactly the same look as in article.
So I created minimal master page, just to play around. But when I'm previewing it and try to change Preview Page, I always got an error, that this page doesn't exist.
And the last problem: so I have the generic page and I click "Snippets", the new tab opens saying: "Sorry, something went wrong". Correlation ID is 3134039c-b656-500e-1c11-f963d30649cf (if needed).
I have the feeling, that I'm doing some silly beginner's mistakes, like not enabling some features or something like that. I would really appreciate any help.
