Just wanted to share this very minor tip but may help someone as it did for me.
I added an ssl certificate to my website.
When I opened my PHPRunner up to make some changes a few days later, I was immediately notified with this popup.

When I first saw this, I was racking my brain to understand what would be the problem.
Then I finally realized that I had the SSL Certificate put on the website and this changed the http to https.
All I needed to do was changed the url to https as circled in red and it was fixed.
