Please help me, I'm desperate !

Help me please ! I don't speak german....

Did you use the Composer dependency manager to install the extension? Did you install the "tng" or "2.x-dev" version, respectively?

I installed tng

my server is it really parameter to use JSON ?
http://testpicardserrures.ecritel.ne...l/php_info.php

Contao : 3.3.7 and 3.4
PHP : 5.3.10-1~dotdeb.0
Mysql :5.0.8-dev
My Json enabled : 1.2.1
fonction array_merge_recursive is enabled or disabled ?

Okay, and how did you do the installation? I would recommend to install the extension via Composer, so that all the dependencies could be resolved. Run the Contao check tool to see if all the requirements are met.

I installed metamodel via FTP

I also tested the 'composer' but the interface is incomprehensible!
I feel like I need to install modules one by one, with the risk of forgetting ...
It's really awful this 'composer' !

I'm having similar issues. Been a long time catalog user and needing to transition, I can't even get a working install to evaluate. I've tried:
Two different VPS configurations
Using a copy of my existing contao 2.11 website
Creating a clean account and install of Contao 2.11, and
Creating a clean account and install of Contao 3.2

In each of these environments I've tried the Metamodels Nightly (under 2.11 this leads to the site becoming unusable do to a infinite redirect, under 3.2 this causes database errors.) as well as composer which never makes it past the initial install before crashing Contao into various database errors.


I have never had more trouble getting something to work than I've had with either Meta-models or Composer.

My problem obviously has the PHP version 5.3 to 5.4 php must have no more error.
I will be update PHP 5.4

it would be nice to indicate the System requirements before installing MM
