Hey, I've recently started a demonstration project for a class; I'm creating a web app in PHP, and I keep randomly running into "Internal Server Error"...nothing is being output to the error logs, and I can't figure out what's even causing this to happen. It's not a single specific script that causes this, I've gotten them on almost every page at some point. After waiting about a minute or so, it goes away, and the exact same page or script runs correctly... What are common causes of an issue like this? Thanks
