I've run into a weird issue while trying to brand my company's SharePoint site. The custom site logo shows up on all pages except for Web Part Pages. When I navigate to a Web Part Page, my logo appears for a split second, then switches to the default SharePoint
image.
Originally I made the change in the Site Settings under "Look and Feel". All pages changed except for Web Part Pages.
So I modified my custom master page and changed the url to my new image. Once again, all pages except for Web Part Pages showed my new logo. All other changes I made to the site appear (and stay), like the site colors and font sizes. I have even moved the
search bar to a different location, and that shows correctly on Web Part Pages.
If I create a "(Welcome Page) Web Part Page", then my logo does show. But we have to have dozen of Web Part Pages and we don't want all of them to be the Welcome Page format.
