Hello,

If you're only having "notice" and no warning messages it won't affect your shop.
Note that when your shop is in production mode you should :
- Disable the Joomla debug mode ("Administration->Global configuration->System->Debug System/Language")
- Set the "error reporting" option of the Joomla configuration to "none"

Regarding these notices, can you tell us with which plugin you're having these notices ?

Thank you.
