Immediately solved my problem

I manage a website with a custom theme we paid a professional company to develop in 2010. We no longer do business with that developer. I ran the free security scan at immuniweb.com and discovered our site’s theme relied on an outdated version of jQuery with known critical security issues.

Not being a developer, this seemed like a problem I might not be able to solve without switching to a new off-the-shelf theme that gets regular updates.

I installed and activated this plugin and cleared my cPanel cache. My site did not break. I refreshed and re-ran the immuniweb security scan. We got a clean bill of health on the jQuery issue. I just can’t thank this developer enough!
