No access to the Dashboard "Debug" section!
Permalink 1 user found helpfulI get no access to the "Debug" area in the dashboard:
Warning: phpinfo () has been disabled for security reasons in / home/htdocs/web56/html/concrete/controllers/dashboard/settings/controller.php on line 460
What can I do? The code in controller.php the situation is no different than other installations where there are no problems. I have that site created completely new online and copied the data from the local installation.

I still have no solution! And no access to php.ini.
The problem occurs after updating to the latest version c5. However, I have switched from the 5.3 on the 5.405.

You may try putting this in your .htaccess file:
php_value disable_functions
I have my doubts the above will work :(
If you create your own php.ini in the webroot, will it over-ride some of the default webhost php.ini settings? If so, just put the following in your new php.ini:
disable_functions =
ob_start();
phpinfo();
$phpinfo = array('phpinfo' => array());
Add "//" to be beginning of the second line so that they look like below.
ob_start();
// phpinfo();
$phpinfo = array('phpinfo' => array());
Save the changes. Access the dashboard and see if that fixes the problem for you. If it does, then you will need to make this change every time you update Concrete5 to a newer version.
big thanks!
This (// phpinfo.. comment out) is exactly the solution!
