I updated the Gantry on March 13. Now the style is not working. I went to Extensions/Template Manager, selected Style, clicked rt_reflex_j16 - Default. The Gantry is not there. I've attached the screenshot.
The website uses Joomla 1.7:

. Maybe the new Gantry doesn't work with the old version of Joomla1.7.
Your template might still work without any problems with Joomla 2.5.x, just try.
For backups: the best and easiest way is to use Akeeba Backup - there is no need for the commercial version, try the free version.
There are a lot of "official" and other videos on Youtube showing you every step.
It's very simple to use and saves you a hell of time!
I don't know if there's an update from 1.7 to 2.5.14 or if you need to update to 2.5.1 first and then to 2.5.14.
I did the Akeeba backup last night, and it was successful.
Akeeba also needs updating but it won't until I update Joomla, so I hope the backup works. I can see the backup is there in the log.
I clicked on "find updates", after "purching the cache", and "there are no updates available" for Joomla. Now I'm stuck.
