Hi Tony.
My plugin only removes the date from individual posts or pages, not from the blog home or other archives.
I posted a much longer response to a review that explains why I can’t hide the date from the blog home or other archives: https://wordpress.org/support/topic/i-love-the-simplicity-of-this-plugin?replies=2#post-7489264
Your theme is not currently outputting the date in a div or span that is hidable. I checked a post from december, and my plugin is loading the CSS file (which does the hiding), but this is the output of the theme:

Note that the date is just within a list item with no class.
To make my plugin work (which again means that it will only work on individual posts and pages) you’ll need to tweak your theme files. I recommend using a child theme for those type of modifications.
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.
Thanks!
