My site is built on WordPress, but I also have many PHP based pages. My Wiki is built from my database. I am trying to show another page of my own site (entitycard.php) in a javascript popup iframe, when hovering over a link to show stats of in-game weapons/armors/items. It works great, but for some reason entitycard.php is giving me the WordPress “Sorry, no posts matched your criteria” issue.

See video below showing the problem on my site, but it working great on localhost. Here is also a screenshot of the issue on my site versus it working in localhost. I appreciate any insight.

Working in localhost versus issue in PROD:

Website where you can see the issue:
https://www.kisnardonline.com/wiki/players.php?name=Tomek

entitycard.php is just a connection to database and then output. Nothing WordPress within it.

Code below for anyone who may want to beg, borrow, steal 🙂

Javascript for popup hide/show:
