I'm having trouble opening my play store I have a galaxy s3 and the play store will not open, I've  i tried every way I can think of to open it but it won't work:

I restarted my phone many times, I've also tried opening it from the application clearing page where it has the option to force close, uninstall and clear data. I also tried deleting some apps, and nothing.

When I click on it to open it opens for a second and displays Play Store on a white screen but in about a second it closes. When I'm doing anything on my phone an error saying play store has unexpectedly stopped and the only thing I can press is an "ok" button. I have also tried downloading apps directly from a website and it doesn't let me, instead it closes the page.

Any ideas?
As the OP didn't report back, it seems safe to assume that the hints given in my comments to the question solved the issue:

One of the general solutions to issues with the Google Play Store app:


From your homescreen, use the menu key/button, and go to Settings › Apps
On the resulting screen, make sure to select the "All" tab
Scroll to the Google Play Store entry and open it
Chose to Clear Cache, then Delete Data, and finally Uninstall Updates1
Reboot your device (either by switching it off and on again, or long-press the Power button to bring up the "Power Menu", where you possibly can select "Reboot" directly)




1: you can try with Clear Cache only to see if that's sufficient, and if not add the other steps one after the other until you succeed
