I cannot use MC admin template as default and it get error 500. I'm using Nginx with PHP5-FPM and FastCGI.
EDIT: It wasn't really problem with Nginx. MC is support for joomla 2.5.1? After i packed up zip to folder /tmp and install from extensions manager and gets error 500. I couldn't use MC as default. Please help! Had tried with apache with same result.
