Easiest quick solution would be to do the following:
Log into you admin panel, then go to Appearance > Editor.
From the drop-down menu on the top right corner, make sure that ‘Twenty Eleven’ is selected.
Scroll down and select Stylesheet (style.css) from the file list that runs down along the right side of the page.
Then search the loaded page for the following:
.entry-meta {
color: #666;
clear: both;
font-size: 12px;
line-height: 18px;
}
And replace that with:
.entry-meta {
color: #666;
clear: both;
font-size: 0px;
line-height: 0px;
visibility: hidden;
}
Finally, press on ‘Update File.’
You may need to refresh the home page a few times before it loads the updated version.
Let me know if this works – it should ??
Best,
