Access denied for Sub Sites

Question

user1 has no access to Site Collection sc1. under SC1 there is a web site ws1 with broken inheritance (unique permissions). user1 has Administrator permission on ws1. but when he browse to ws1 he gets Access Denied.

You have created your own master page mymaster.master and used a module (VS module template) and a Site scoped feature (which contains the module) to deploy your master page. Can It be the reason? and how I can solve this problem thanks. here is the element.xml of the module:

<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
  <Module Name="MasterpageModule" Url="_catalogs/masterpage">
     <File Path="MasterPageModule\mymaster.master" Url="mymaster.master" Type="GhostableInLibrary" />
  </Module>
</Elements>  

Answer 1

The most common issues:

• Your master page hasn't been approved (in feature receiver) so it's left in Draft mode
• Your master page includes some code which access something the uses don't have access to
• Your master page includes references to files (images/stylesheets/...) that the user don't have access to

Answer 2

Does your subsite inherits the master page from site collection. Generally master page gallery resides in the site collection level. So may be user1 doesn't have access to that library. And it is causing the access denied error.
