README

Contao is an Open Source PHP Content Management System for people who want a professional website that is easy to maintain. Visit the project website for more information.

System Requirements

Web server
PHP 7.2+ with GDlib, DOM and Phar
MySQL 5.5.7+
InnoDB with innodb_large_prefix enabled

InnoDB Large Prefix

MySQL versions prior to 5.7.7 do not have the innodb_large_prefix option enabled by default. To enable it in one of these versions, add the following to your my.cnf file:

innodb_large_prefix = 1
innodb_file_format = Barracuda
innodb_file_per_table = 1

If the option cannot be enabled on your server, please configure a different database engine and character set in your config/config.yml file:

doctrine:
    dbal:
        connections:
            default:
                default_table_options:
                    charset: utf8
                    collate: utf8_unicode_ci
                    engine: MyISAM
