Server

After the transition to ip address for a domain name in the log the error occurred:

Argument 8 passed to OC\Core\Controller\AvatarController::__construct() must implement interface OCP\Files\Folder, null given, called in /var/www/owncloud/core/Application.php on line 96 and defined at /var/www/owncloud/core/Controller/AvatarController.php#88

My actions are the steps:

  1. Step
    I create a file in /etc/apache2/conf-available/ with the name owncloud.conf
    and he wrote in his configuration

    <Directory “/var/www/owncloud”>

     SSLRenegBufferSize 10486000
 LimitRequestBody 0

 Options +FollowSymLinks
 AllowOverride All

 <IfModule mod_dav.c>
   Dav off
 </IfModule>

 SetEnv HOME /var/www/owncloud
 SetEnv HTTP_HOME /var/www/owncloud

    <Directory “/var/www/owncloud/data/”>

    just in case if .htaccess gets disabled

    Require all denied

  2. Step
    I create a file in /etc/apache2/sites-available/ with the name owncloud_ssl.conf
    and he wrote in his configuration

    Header always set Strict-Transport-Security "max-age=15768000; includeSubDomains; preload" 
                 ServerName test.test.com
             ServerAlias www.test.test.com

             ServerAdmin webmaster@localhost

             DocumentRoot /var/www/owncloud

             ErrorLog ${APACHE_LOG_DIR}/error.log
             CustomLog ${APACHE_LOG_DIR}/access.log combined


             SSLEngine on
             SSLProtocol all -SSLv2


             SSLCertificateFile      /etc/apache2/ssl/owncloud.crt
             SSLCertificateKeyFile /etc/apache2/ssl/owncloud.key


             <FilesMatch "\.(cgi|shtml|phtml|php)$">
                             SSLOptions +StdEnvVars
             </FilesMatch>

             <Directory /usr/lib/cgi-bin>
                             SSLOptions +StdEnvVars
             </Directory>


             BrowserMatch "MSIE [2-6]" \
                             nokeepalive ssl-unclean-shutdown \
                             downgrade-1.0 force-response-1.0

             BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown

     </VirtualHost>

  3. Step
    Activated, these two configuration using commands

a2enconf owncloud.conf
a2ensite owncloud_ssl.conf

  1. Step
    apache2 restart

  2. Step
    Add to config.php

    ‘trusted_domains’ =>
    array (
    0 => ‘...’,
    1 => ‘test.test.com’,
    ),

I wanted to make owncloud worked test.test.com

Please tell me what I did wrong?
Why is this error?
Thank you!
