MM Installation for 2.1 and Older

Installing MM 2.1 for Contao 4.4

The installation requirements for MetaModels 2.1 are:

  • a running Contao 4.4.x (LTS) and

  • PHP 7.1/7.2

  • MySQL from 5.5.5 (InnoDB), MariaDB (without strict mode)

Higher versions of Contao and/or PHP are possible but not officially supported.

Installing MetaModels 2.0 for Contao 3.5

Installing MetaModels 2.0 for Contao 3 requires a Contao LTS version, i.e. Contao 3.5.x — as well as the system requirements equivalent to the Contao LTS.

Since January 2018, MM 2.0 requires at least PHP 5.6.

When upgrading from a “nightly build”, it can happen that two tables from the MM Core are missing and cannot be created by the Contao migration. If this is the case, please create the following two tables manually:

  • tl_metamodel_dcasetting_condition.php

  • tl_metamodel_searchable_pages.php
