Accidentally deleted /var/log/apache2 and now can't restart apache

Question

I'm using Ubuntu 14.04 and apache2 and ispconfig 3. Just a few hours ago I accidentally deleted /var/log/apache2 folder include files, now my server can't restart apache2, how can I restore them? or is that log folder and file will auto create by system, when reboot server?

When I restart apache2

 * Restarting web server apache2                                         [fail]
 * The apache2 configtest failed.
Output of config test was:
AH00548: NameVirtualHost has no effect and will be removed in the next release /etc/apache2/sites-enabled/000-ispconfig.conf:61
(2)No such file or directory: AH02291: Cannot access directory '/var/log/apache2/' for main error log
(2)No such file or directory: AH02291: Cannot access directory '/var/log/apache2/' for error log of vhost defined at /etc/apache2/sites-enabled/000-default.conf:1
AH00014: Configuration check failed
Action 'configtest' failed.
The Apache error log may have more information.
