Login error message scan

The scan

This scan checks the login page doesn't reveal too sensitive information in case there's an error. 

The fix

SecuPress will display a less specific message to the user when there's an error.

What if the fix doesn't work ?

Try to find the plugin preventing SecuPress from modifying the error messages and deactivate it. The problem may also come from a code snippet added to your theme's  functions.php file.
