Yosemite 10.10.5 Update Disabled Apache

I've just updated Yosemite on a MacBook Pro (17-inch, Mid 2010) from v 10.10.4 to 10.10.5 and now my local development environment is disabled.

Some sites I've researched and changes I've adopted:

Self-signed SSL Certificate on Mac Yosemite

http://brianflove.com/2014/12/01/self-signed-ssl-certificate-on-mac-yosemite/

- created working SSL Certificates and configured Apache to use them

Local SSL websites on Mac OSX

- made changes to httpd-vhosts.conf

Fix broken Apache config after Upgrading to OS X Yosemite

- made changes to httpd-vhosts.conf

Apache issues after upgrade to Mac OS X Yosemite (see comments by 'nicholos')

http://enzolutions.com/articles/2014/10/19/apache-issues-after-upgrade-to-mac-os -x-yosemite/

- made changes to httpd-vhosts.conf

After any change, I did a '$ sudo apachectl configtest', and confirmed a 'Syntax OK' before moving on, then a '$ sudo apachectl -k restart'.

After checking both the Apache error_log and the local development site error_log multiple times and resolving any errors after changes, I do not see any errors.

Now I stuck with, "Firefox has detected that the server is redirecting the request for this address in a way that will never complete," even though this was not a problem before the Yosemite v10.10.5 Update.

Does anyone have a working solution? Thanks
