Requirements

We have tested this app to run on shared web hosting providers, VPS and dedicated server solutions. App was tested to run on both cPanel and DirectAdmin, which are two most popular platforms. Bellow is list of all requirements. They may seem scary, but in reality most of them are common and are included as standard. Most important thing is, that your web hosting provider supports PHP 7.3+ and has MYSQL 5.6+.

List of minimal requirements for: 2MAX.io Classified Ads
