[Koha] Webserver not working

hi, my web server has stopped working and when I try to stop and restart Apache I get this error message # apachectl stop apache2: Syntax error on line 230 of /etc/apache2/apache2.conf: Syntax error on line 5 of /etc/apache2/sites-enabled/library: Could not open configuration file /etc/koha/apache-shared.conf: No such file or directory Action 'sto and in fact I can not see that file in that folder, so what has happened to that file, I just did backup the other day via sudo koha-dump library do you think this has created any problem?
