Trouble syncing gmail

[AC Question]

I have a Galaxy 4.2.2 with what appears to be plenty of memory, but now my gmail can't sync because there's not enough storage space, according to the message. Any advice on what to check or how to fix?
Thanks CT

Welcome to Android Central! Tell us the exact model of Galaxy phone you have, because there are lots and lots and lots and lots and lots and lots of different kinds. Some of them are flagship superphones, and others are entry-level not-so-superphones, with very little internal memory.

If you can, please post a screenshot of your Settings>Storage​ screen.
