Nexus S won't sync contacts anymore

Hi everyone,
all of a sudden my Nexus S on 4.1.2 has stopped syncing my google contacts. And only my contacts, see screenshot below. No changes to settings were made, this came out of nowhere.
Does anyone have any idea what's going on and how I can solve this?
Tried this so far:
- Turning the phone off and back on
- Unchecking the box and re-checking it
- Options - "Sync now" makes everything in the list sync except my contacts of course :(

[Only registered and activated users can see links. Click Here To Register...]

Thanks in advance!

First, try clicking the circular arrows. If that doesn't work, uncheck the box, then check it again. Finally, if all else fails, delete your Google account and re-add it.

Have you found a solution?

I have the same issue with my Nexus 7, same android version and same problem.

Thank You

Hey, it's me again.

I think I found a solution, this is what I did:

1. Go to configuration, manage aplications.
2. Find Contacts app then delete cache > delete data > force close
3. Find Contacts Sync then delete cache > delete data > force close
4. Find Contacts Storage then delete cache > delete data > force close
5. Go to config, accounts & sync, and sync all. It will take a long time now to sync all contacts but it worked ok.

I hope this hepls :)
