Specified condition "$(CleanWPPAllFilesInSingleFolder)" evaluates to "" instead of a boolean.

Question

At first my only problem was that while trying to publish I clicked on Start Preview and got this error:

Specified condition "$(CleanWPPAllFilesInSingleFolder)" evaluates to "" instead of a boolean.

then searching for solution on the internet made my problem worse to the point that I can not load the project any more with the same error.

C:\Users\Syed Farjad Zia Zaid\documents\visual studio 2013\Projects\SageInventrica\SageInventrica\SageInventrica.csproj : error  : Specified condition "$(CleanWPPAllFilesInSingleFolder)" evaluates to "" instead of a boolean.  C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\Web\Microsoft.Web.Publishing.targets

Naturally I tried to search for a solution and tried all possible combinations of deleting .user, .suo, closing and opening Visual Studio etc but nothing helped me except for deleting this File:

C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\Web\Microsoft.Web.Publishing.targets

But then I can not publish a zip getting the error:

The target "Package" does not exist in the project.

and when I try to publish to Server Directly I get the error:

The target "MSDeployPublish" does not exist in the project.

I have been trying to find the solution for this for about 2 days now. May be I am not looking at the right places but I really need help to fix this...

Thanks

I fixed this problem by restarting Visual Studio as Admin, and publishing again, but making sure NOT to preview the publish actions.
