IPhone 4S, no apps allowed access to photos

None of my applications, eg facebook twitter tumblr, have access to my photos
I have tried changing the privacy settings but there's no option to
The only thing in the photo privacy section is facebook, however the slider is faded out so I can't change it

Anyone know what the problem is and have a solution?

This might be happening due to a bug > http://blog.s-d-solutions.com/2013/04/iphone-4s-no-apps-allowed-access-to.html

It won't let me go on my apps and let me access my photos. I tried going to privacy settings and it won't let me turn it on. I don't know what to do.
