Hi, I have deleted some unused visualforce pages and their controllers from beta package, all the references to these components are also have been removed in the package but I am not able to upgrade to this beta package from latest release package. I have undeleted the controllers successfully and I tried undeleting those visualforce pages but the undelete button is not available for them.
While upgrading this error: 
Salesforce has blocked this package upgrade because the new package version removes some Apex code that one or more Visualforce pages or global Visualforce components need in order to function. Please contact your partner with this error information. Provide these component names to your partner. Visualforce Pages: ForgotPassword, ChangePassword, SiteRegister.

HI Friends,

     I deleted some pages from my managed package, Now I want to get it back. Is there any way to do it. If you need any more information please let me know.

Thanks,
Naresh.
