I am developing a wordpress theme for my school. It was working very fine, just one fine day i decided to check it against theme check plugin. it is able to pass all the criteria but when ever i enable debug mode it start displaying a lots of error on the backend, and suggesting settings-api instead of my _post method.
Later on, i downloaded some famous free themes from the internet and to my surprise none of them is able to pass the criterias in debug-mode either on front-end or in backend. But they are working fine.
My question is - is it theme check benchmark for a quality wordpress theme?
Kindly guide me.
