Your routing is NOT working well.
Please activate mod_rewrite and .htaccess.
Or uncomment "//Configure::write('App.baseUrl', env('SCRIPT_NAME'));" in app/Config/core.php and remove all .htaccess.
I tried the last option.
Then the errormsg dissappears, and a page looking a lot like redmine appears:
Error: An Internal Error Has Occurred.
I found some other forum suggestion, which gave this result.
candycane/cc_install/cc_install/route was not found on this server.
Suggestions?
