Removing date comments closed Constructor theme

Hi,

Theme used: Constructor

Im having a lot of issues removing both the date and ‘comments closed’ underneath every page in my wp site thats under construction. I did countless searches on the subject, removed everything needed according to possible solutions and added a display:none to the .commentsclosed in the css stylesheet. No result. To be honest, it is driving me crazy.

Im am a beginner at this stuff, so please be clear with any solution you might give. The site is located at

this location thanks in advance.
