404 for admin after changing Default-Website

[webyourlife]

Hi,

i'm running a Magento 2.1.2 as a Multi-Shop and changed the Standard-Website in the Admin-Area. Now i'm getting 404-Error for every try to reach the backend/admin-Website - as well if i use domain1.com or domain2.com. There is an redirection for my custon admin-link to: domain1.com/myadmin/admin/index/index/key/f33b8fe5244c056d1d62a4f919e889feec7a49b12c00a33d024cff077e0af818/?SID=g5a620imdfpf969mc9rf71cid6

It worked perfectly before changing the standard-website. There is an .htaccess-file in the root directory. I didn't change the /app/etc/env.php in line 5 so it is the same as before ('backend' => array ( 'frontName' => 'myadmin', ...).

Does anybody has an idea what else i can try? Clearing the cache manualy?!

Thanks Joachim

Puuhhh ... it helped me to delete everything inside of /var/cache/

Now everything is fine again. Praise god and the team of magento ...
