Was working great but now..

Hi there, can you send along a link to your site so that I can check it out? Thanks for using my plugin!

Sure thing. Here is the site. Thanks for the help.

So in looking at your site, the plugin is working. (on this post, for example the plugin is loading a stylesheet that is designed to hide the date: https://potential2success.com/for-entrepreneurs-guest-post-5-real-world-strategies-for-launching-a-home-based-career.html but on this post it is not: https://potential2success.com/the-rapid-promotion-project-how-to-get-promoted-every-8-months.html ) If you disable my plugin, does the date appear on the old posts?

I suspect your theme doesn’t have a date on it, but I don’t know. Can you deactivate my plugin so that I can see where the date normally lives? Thanks!
