Note: You are currently viewing documentation for Moodle 2.4. Up-to-date documentation for the latest stable version of Moodle may be available here: report/security/report security check displayerrors.
If PHP is set to display errors, then anyone can enter a faulty URL causing PHP to give up valuable information about directory structures and so on.
If you go to Settings > Site administration > Reports > Security overview, displaying of PHP errors status is Warning. on your web server, locate php.ini, open it in wordpad and search for "display_errors". Ensure that it is set to "display_errors = Off" and then save. If this is on a hosted webserver (e.g. network solutions), insert "display_errors = Off" into the php.ini or call them for instructions (took 2 minutes) on how to do it. Very simple to modify.
Please note it is not enough to change debugging level in Moodle settings because we need to prevent errors in scripts that are not supposed to be accessed directly.
