Why don't my contacts show up?

[AC Question]

As of this morning, when I try to hit my contacts, nothing shows up. Not one contact. I have a lot of contacts on my phone (I have LinkedIn synced to it). But now none of them, or my other contacts show up. Help!!!

Welcome to Android Central! Which phone? Are the contacts mostly associated with your Google account, the Phone account, or LinkedIn? Go to Settings>Accounts, and select Google, then your Google account, and make sure Contacts is checked. Do the same for LinkedIn.
