[Scorpions95]

Hi dm
i try to install mchat on my test board but it shows an error
here is it

[quote="kasimi"]Open [c]ext/dmzx/mchat/ext.php[/c], find [c]$config = $this->container->get('config');[/c] and on a new line above, add [c]return true;[/c]

Now enable again. Do you still see any errors?

By the way, the latest mChat is 2.1.2.[/quote]
