System requirements

These are the basic system requirements for a Contao webspace:

webserver: Apache or IIS PHP:minimum version 5.2 PHP extensions:

• GDlib, used for image resizing
• SOAP (optionally), needs to allow external transfers so that you can use the extension repository within your Contao-backend
• mbstring (optionally), needed for multi-byte character handling
• mcrypt (optionally), needed for data encryption

MySQL: minimum version 4.1, though I definitely recommend version 5.x; MySQLi is also supported browser (for Contao backend): a modern internet browser … don't even think about Internet Explorer 6 ;-)

==Recommended PHP configurations

Safe mode: Off Maximum execution time: 30 or greater Memory limit: 16M or greater Register globals: Off File uploads: On Upload maximum filesize: 8M or greater GDlib extension: On SOAP extension: On

Tip: I recommend using the system check.
