I discovered that the problem is apache.

in the error.log there is this error:

unable to start piped log program ' /usr/sbin/vlogger -s access.log -t "%Y%m%d-access.log" /var/log/ispconfig/httpd': No such file or directory
Unable to open logs


why?

thanks!

What are the outputs of

ls -l /usr/sbin/vlogger

and

ls -la /var/log/

?
