Welcome to DevKinsta @adamk22 and @visualvoodoostudios ! While you could increase it to more than 256MB, requiring more than 256MB likely indicates an issue on the site that I believe should be investigated. It’s extremely rare to need more than 256MB. That being said, the guide @adamk22 posted earlier provides instructions on how to increase it. I’d start with 512MB and go up from there if more is needed.
