We don't want the Author information published on our web pages, We selected hide for the Author in both Item view options and Item view options in category listings. have checked the K2 Parameters and can't see anything that would turn this off.

Hi. Regarding your issue:

1. Check again your settings. In case you are using a module then the setting can be found in the module parameters.
2. Ensure that you have the latest version of K2.
3. Ensure that you do not have any custom K2 template overrides.
