It's recommended not to install that many plugin for your wordpress site as it slows down our beloved CMS. However if there isn't any notion to get our hands dirty with codes then there is no other soultion but hit up the plugin menu an add some of theese to our installation:

The optimal solution is of course to get down to the code level and sort it out there.

If our template supports custom css then it's super easy to solve the problem. Simply add this line of code to the custom css box and problem solved:

.entry-date {
display: none;
}

If we have chosen a template without css support then swap it as it will sour our life down the road anyway. But of course if there is no chance for theme swap there is always chance for child themes and mess with the css code there.

 

 

 

.entry-date {
display: none;
