Hello Graka.
Please, provide us your error.log (or whatever php error log) file contents.
If you are running the Apache web server, add this to the .htaccess file in toaster root
php_flag log_errors On
php_flag ignore_repeated_errors On
php_value error_log /path/to/your/erro/log/file
Also can you provide to us phpinfo configuration.
Thank you.
