**Your software**  
My Mautic version is: 4.1.1

**Your problem**  
Hi everyone,  
I am on Mautic 4.1.1  
I have this problem:  
When I go to the menu Channels → Email the link doesn’t work.  
If instead of clicking with the left button I do it with the:  
right click → open in a new tab  
it opens the link but I get error 500  
Any ideas?

I’m also having this problem, but I also can’t access Config and Themes.

```auto
mautic.CRITICAL: Uncaught PHP Exception Symfony\Component\Debug\Exception\FatalThrowableError: "Type error: Argument 1 passed to Mautic\CoreBundle\Helper\ThemeHelper::shouldLoadTheme() must be of the type array, null given, called in /var/www/html/app/bundles/CoreBundle/Helper/ThemeHelper.php on line 622" at /var/www/html/app/bundles/CoreBundle/Helper/ThemeHelper.php line 642 {"exception":"[object] (Symfony\\Component\\Debug\\Exception\\FatalThrowableError(code: 0): Type error: Argument 1 passed to Mautic\\CoreBundle\\Helper\\ThemeHelper::shouldLoadTheme() must be of the type array, null given, called in /var/www/html/app/bundles/CoreBundle/Helper/ThemeHelper.php on line 622 at /var/www/html/app/bundles/CoreBundle/Helper/ThemeHelper.php:642)"} []

I found a solution here:  
[Argument 1 passed to Mautic\CoreBundle\Helper\ThemeHelper::shouldLoadTheme() must be of the type array, null given · Issue #12230 · mautic/mautic · GitHub](https://github.com/mautic/mautic/issues/12230)

This worked for me!

" Solution worked:  
Update this line :  
private function shouldLoadTheme(array $config, string $featureRequested): bool  
to  
private function shouldLoadTheme(array $config = NULL, string $featureRequested): bool  
in the file: mautic/app/bundles/CoreBundle/Helper/ThemeHelper.php
