Okay so ive been attempting to make some customizations to the orangesinglelevel.master with sharepoint designer. When i open the my site in sharepoint designer and navigate to the _catalogs folder and attempt to make changes to the default.master page. None of the changes are shown on the website. I've also tried going to the 'site settings > master galleries > edit with sharepoint designer' but that opens the same default.master page and still no changes are evident.
I have almost no clue how to edit the information that is being displayed on the website and i have absolutely no clue where it is coming from.
Is there a difference between master pages and themes? im i making changes to the theme and not the master page? please any help would be much appreciated i cannot implmenent any of my ideas because i have no clue what information is being display.
Also when i click design view inside of sharepoint designer it does not display the orange theme.
