Try clearing cache and data of the Play Store app. Settings>Apps>All Apps>Google Play Store and hit Clear cache/data. This usually fixes errors on play store. Hope I helped

I am having the same problem. I tried what you just told but it doesn't solve the problem.
It has started since I flashed factory image on my Nexus 5.
