Fix 1:
Go to Settings > iCloud> Documents & Data. Toggle the switch to Off and allow your system to update. Next go to Settings > General > Keyboard and delete of all your installed keyboard shortcuts. Then go back to Settings > iCloud > Documents & Data and toggle the switch to On to re-enable Documents syncing through iCloud. You will need to reboot your device after this which may take a little bit of time but all of your shortcuts will be restored and should be functioning normally again.
Fix 2:
Go to Settings > General > Keyboard and select the keywords option. Select the currently enabled keyboard and change it to a different language. Without leaving the keyboard settings panel, re-select the native keyboard that you were originally using. Next go into a text editor and try some of your keyboard shortcuts and you should find that they are all working normally again.
