Yes, you can do something from the Editor area. The following is what we’d call a “hack.” It will vanish next time the theme is updated, and the unwanted text will reappear.
In the editor, you want to have the file called “styles.css” open.
Scroll down about a third of the way to line 1045 till you see a heading like this:
/**
* 5.2 Entry Meta
* ----------------------------------------------------------------------------
*/
On the line after all this, we are going to paste a little bit of CSS code.
If you want to remove only the red text meta-data that is right above the philosopher’s head, paste this:
.home #post-146 .entry-meta {
display: none;
}
If you want to get rid of both that and the meta-data that follows the quote in the black bar that’s a little farther down the page, paste in this instead:
.home .entry-meta {
display: none;
}
Save it and check the page. Let me know if you have a problem or if there are unexpected changes.
My disclaimer: This should accomplish what you want, but it is NOT the preferred way of making this change. If you can at some point get access to the files on his server, go the Child Theme route and make the change in the template file called “content.php”. Once you have a child theme running, it’s easier to make additional modifications down the road.
