hello,
i will try to help you but i need more information.
- which PHP version ? something particular in the configuration
- do you use URL rewriting ?
- any other information in the error 500 page ?
if you are runing your project with the production environment
(default one), please check it with a developement environment by
setting th 'env' option like this in your configuration() function
option('env', ENV_DEVELOPMENT);
This will help us debugging by providing more information in error
outputs.
