Date Not displaying in posts

Please, post your website URL and I will look into it.

Date is there by default and unless removed/hidden buy your custom implementations, it should work just fine.

You call yourself a developer but you have no idea about a single CSS that you have wrote/added yourself in style.css.

Meta information is not displayed by obvious reason. Here is snipped copied from your style.css

.entry-meta {
  margin-bottom: 30px;

  display: none;
}

This part
display: none;

mans that you wanted to hide it.

I removed it and It’s still the same i niticed that my tags are not also displaying. Please help me
