[Q] Sync Issues with Custom ROM

After installing Asylum Naughties ROM (which is fantastic btw) and I started experiencing sync issues. I am unable to receive emails/whatsapp messages unless I open the app...and then it works fine. I thought it was a force close issue and even if i let the app run in the background, it ceases to receive messages after sometime. The sync settings is set to "auto-sync app data". I've tried other ROMS (Carbon and SlimKAT) and I seem to be facing the same problem.

Thanks in advance
