[Koha] Changes not getting reflected on OPAC page on changing of net connection[ip addr].

Hello, i was using my laptop in institute which had a proxy server, made some changes to the /home/koha/opac/htdocs/opac-tmpl/prog/en/includes/masthead.inc file which was reflected on my OPAC page.. Came home, had to change the ip since koha was not working [changed 1. /etc/apache2/apache2.conf ServerName 127.0.1.1 2. gedit /etc/koha/koha-httpd.conf ## OPAC <VirtualHost 127.0.1.1:8086> ].. When i opened opac[127.0.1.1:8086/], the opac page looked normal(none of my changes existed) but the changes made to this file, did not change /home/koha/opac/htdocs/opac-tmpl/prog/en/includes/masthead.inc any ideas on Wat i should do to reflect the changes on the opac page?? Thank you..
