Hi, I created a master page by using Design Manager. I uploaded the html file and Design Manager converted it to a master page. I created css, js and img folders in Style Library and uploaded the files to the applicable folders. However, when I view the site none of the styles are displaying.
When I use IE Developer tools and hover over an element it's showing corev15.css as the stylesheet when it should be bootstrap.min.css or one of the other two css files that were included.
I had read that I need to register the css by adding <SharePoint:CssRegistration> under the one already present for corev15.css i.e.
<SharePoint:CssRegistration Name="Themable/corev15.css" runat="server"></SharePoint:CssRegistration>
However, when I try to add it to the html file I get an error saying that it needs to be an aspx file. When I try to add it to the master page I get an error saying "Server error: this file may not be moved, deleted, renamed or otherwise edited".
As well, a master page that was created by another person, that is displaying correctly does not have this added.
Any ideas? Thanks in advance for your time!
