You might be better off asking in the XDA thread of the custom ROM about your issue. It's a bit too vague for us to help you with that here.

We don't know the custom ROM you've used.
We don't know the device you're using it on.
We don't know how you've flashed said custom ROM.
We don't know where you got your gApps or which package you've installed.
We don't know if the custom ROM you've used is up to date or if you've just found it on some random website that hasn't been updated in months.
Etc etc etc.
