3. Recommended PHP Configuration Limits

Many issues that you may run into such as; white screen, demo content fails when importing, empty page content and other similar issues are all related to low PHP configuration limits. The solution is to increase the PHP limits. You can do this on your own, or contact your web host and ask them to increase those limits to a minimum as follows:
