Remove information from Post Article Theme

Hi

i am using WordPress 4.5.3 and the Effective News Theme. I could set up now everything fine but there is information in the article post which i want to exclude and not show (example Post: LINK)

Under the titel i want to exclude and not show the categories for example and also the tags at the bottom of the article should not be shown.

I already tried all files shown in the design editor but found nothing. Does someone have an idea where to find those things?

Kind Regards
