Is it all text notifications or just SMS Pro and Chomp SMS? (Guessing it's stock SMS app since you uninstalled SMS Pro and Chomp SMS.) Go to the Stock SMS App > Softkey (Menu icon left of Home button) > Settings: See if Notifications is checked. If so, I suggest tapping the Softkey (Menu icon left of Home button) inside the Settings menu, then tapping on Restore Default Settings. If that helps or does, please let me know!
