Help with a rejection, how can I be more clear next time?

wordpress

Hi guys,
It isn’t the first item I have on Codecanyon although the last one I submitted was a few years ago.
I was told that my WordPress plugin doesn’t follow the quality standard (Although I checked and it does :frowning: )
The reviewer told me to try to check against the “plugincheck WP plugin” , but I am not sure that I am using the correct one, could you please point to me where it is?
