Hi Sydney,
The home page is what WordPress calls an “archive.” My plugin removes the date from single pages and posts. So this post (the most recent) would have the date removed: https://loveandrespectnow.com/2014/12/from-my-heart/ while the home page would not have the dates removed: https://loveandrespectnow.com
And if you look at the source code on that single page above (right click and “view page source” or something like that) you can see that on line 2001, there is a call for my plugin’s stylesheet.
Stick with me, I’m getting to the point.
The fact that the stylesheet is being called is good, and means that the plugin _can_ work on your site. But the theme (it looks like Starkers or a Starkers child theme) is not putting the date inside of something to make it hideable.
That is a bit advanced, but basically you modify the theme files (I recommend using a child theme) and put the date into a div or span with the class “date” or similar.
I’m happy to help with that, but it falls outside of the scope of free support for my plugin. If you need that type of support, I can get you a quote by filling out the contact form at my website.
