You have a bit of a challenge on your hands.

First you need to take a backup of both your sql database and your gallery files. That should be the easy part.

You then have to update in steps from your current version  via 5.x to the latest version. That is where the challenge begins as you are now on a late version of PHP. So somehow you need to be able to run an earlier version to do the upgrade. That can be done locally using WAMP or similar, working on your backup rather than your live data to do so. If you are totally struggling to do this then I will see if I can help.

The update.php ?
Yes i've done it.
I'd needed to put php in 5.5 to execute the script
Now i've this error message : Coppermine critical error:
The group table does not contain the Anonymous group !
So

Is the gallery on your own server or in a hosting account?

If you will send me a private message (PM) with the information and credentials I would need to access your gallery server, I will try to help you upgrade to the latest CPG (1.6.13).

It's on hosting server !!!
