(Solved)Apache2 virtualhost problem for Wordpress 5 local config

Hi everyone,

I have a problem with Wordpress Apache2 Virtualhost and rewrite through .htaccess.
Update:
After deleting the cache several times and also completely stoped apach2 and start it again it works.

My config looks like this for apache2 virtualhost:

<VirtualHost *:80>

     DocumentRoot /var/www/example.com/
     ServerName example.com
     ServerAlias www.example.com

     <Directory /var/www/example.com/>
        Options +FollowSymlinks
        AllowOverride All
        Require all granted
     </Directory>

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

</VirtualHost>

I also have this in my /etc/hosts:

127.0.0.1 example.com

If I enable the vhost in apache2 with sudo a2eniste exmaple.com and reatrt the server with sudo systemctl apache2 reload and also test the config with apachectl configtest. All is correct and I get

apachectl configtest                                                                   
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message
Syntax OK

Also the permissions on example.com and on the files and folders:

ls -ail /var/www/example.com
