any help please?

Hi,
they are not error messages, but just warning messages. The warning tells you how to cure the messages - "Use GPIO.setwarnings(False) to disable warnings."
That just hides the warning, a better solution is to stop the condition that produces the warnings. You should be able to find the solution if you search.
If you've connected up the LCD correctly, it should still work.

Hope this helps,
Texy
