The update to 7.13.48 included an update to Apache to bring it to version 2.4.62. Apache 2.4.62 made changes to how subdomains work.
We updated the sudomain logic for our vhosts so that it is compatible with the new expectations, however, it has been brought to our attention that, due to some caching, the vhosts on some servers did not update to the new logic. This can cause subdomains to return with a 404 error.
So, if, after the update to 7.13.48/ Apache 2.4.62, subdomains are suddenly showing a 404 after the update, please run the following commands. These will recreate the subdomain logic template, write the vhosts so that it is using that template, and restart Apache so the changes go into effect:
touch /home/interworx/etc/templates/http/vhost/subdomains.tpl
~iworx/bin/httpd.pex --write-vhosts-all
service httpd restart
If after running the above commands, the subdomains still show a 404 error, submit a ticket to InterWorx support at httpd://support.interworx.com
