Delegate Control not showing on Master Page in SharePoint 2013
This issue occurred because the value for ControlSrc in Elements.xml is not correct. The path to the user control must point to the file in the folder structures for SharePoint 2013(15 Hive)
Refer to the .cs file for the webpart which has the path to the user control file generated by Visual Studio. Generally the path must start with “~/_ControlTemplates/15/…”
Cannot find Site collection features
It’s a simple problem, the account you’re logged in isn’t the site collection administrator so all those options don’t show up under Site Settings.
Log in using the Site Collection Administrator account or set your account as the Administrator and try again.

However for some reason, it’s required to set ControlSrc to “~/_ControlTemplates/15/…” or else the control won’t be used.
