</div>

Example IMAP password: 6Q{%X|NQgsw8Cd7B1+%j  
  
Reaction of Mautic: Crash  
  
Seems to be the % char  
  
Error in log file:  
  
PHP message: exception ‘Symfony\Component\DependencyInjection\Exception\ParameterNotFoundException’ with message ‘The service “mautic.security” has a dependency on a non-existent parameter “x|nqgsw8cd7b1+”.’ in /var/www/mautic/vendor/symfony/dependency-injection/ParameterBag/ParameterBag.php:84

Yo I found it !

It is the % in the string that fuck this up…

you can change it in the setting file (not the db…)

Here’s how :

edit the file local.php in /app/config and change the part that cause problem (in your case the passord string for anythig that don’t have % like “this bug is a huge time waster” 🙂 and you will have access to your site again.

Hope this help !

$ signs in passwords also won’t work, as I commented here [https://github.com/mautic/mautic/issues/3195](https://github.com/mautic/mautic/issues/3195)
