Hi, I am not sure if solution to this issue is already posted?
I have my feature which copy my custom.master which is copy of default.master from hive to master page gallery of web. The problem is that everything works fine with feature activate and deactivate but when I retract the solution from the server. All pages
except site settings page stop working saying "file not found". I redeploy the solution, it starts working again.
Looks like the retract is deleting default.master as well? I have this issue in 2010 as well. Any help will be appreciated.
