[solved] Custom Route.admin - My Info page broken or CSS ignored

[cluster]

Blesta 5.10.1
PHP 7.4 FPM
Debain 11

error details
when declaring a custom admin folder name, a UI error occurs under "My Info"
The variable for the custom admin folder name (Route.admin) may be missing in "My Info" page ...

steps to reproduce
change Route.admin in /config/routes.php
e.g.

Configure::set("Route.admin", "bltestadmin");

Clear cache: Settings > System > Staff > Staff Groups > Save with no changes

Logout > Login and click "My Info"

Sorry guys, the problem does not seem to be caused by changing the admin folder name, I changed it again to admin for testing and the info page still looks broken ...
mytestdomain.tld/admin/settings/system/staff/edit/1/

Blesta debugging is enabled, but no errors are shown ... not even in the apache error.log

I am currently testing a few custom modules & plugins using a DEV license installation ... could that be the reason?

OK ... I have renewed my Support and Updates services today. There is currently no productive installation in use and I am only testing w/ the dev license.
If I remember correctly this is probably caused due to the dev license (I hope so), so that's not a problem 😉

It looks like no CSS is being loaded. If you use your inspector you should be able to see the request for CSS files and the response of your web server. Maybe some files are missing? Or maybe they are being blocked or not loaded due to your .htaccess file.
