I have the same issue. My installation is through Softaculous on a cPanel-Server with this configuration:
Linux Distro: CentOS release 6.5 (Final)
Server Software: Apache/2.4.7 (Unix) OpenSSL/1.0.1e-fips mod_bwlimited/1.4
PHP Version: 5.3.28 (PHPInfo)
cURL Version: 7.24.0
MySQL Version: 5.1.73-cll
Any solutions? Console in Chrome gives this error message:
Failed to load resource: the server responded with a status of 500 (Internal Server Error)
Otherwise it's a great software suite. Hats off to the developers!
