Some shared hosting environments will disable certain common PHP methods and configurations that affect Craft features.

Required Database User Privileges

The database user you tell Craft to connect with must have the following privileges:

• REFERENCES
• LOCK TABLES

PostgreSQL

Control Panel Browser Requirements

Craft’s control panel requires a browser that supports JavaScript modules (opens new window).

Windows and macOS

• Firefox 67+
• Chrome 63+
• Safari 11.1+
• Edge 79+

Mobile

• iOS: Safari 11+
• Android: Chrome 81+ or Firefox 68+

Craft’s control panel browser requirements have nothing to do with your actual website. If you’re a glutton for punishment and want your website to look flawless on IE 6, that’s your choice.
