Let me take this moment to reinforce Chris's note about running from Master: it can be dangerous! If you aren't comfortable working with git, I would encourage you not to run from Master. Although it is in theory possible for something like this to happen on a stable branch (e.g., 3.6.x), it's much less likely to happen. If, for whatever reason, you *have* to use the Master branch, test the exact version you want to use on a staging server before applying it to a production server.

Hi Katrin,

How do I go about installing this patch onto my system, I can be a bit clueless on installing these sorts of things on our Linux installation which runs Koha.

If you could get back to me, or anyone please, with how to fix this problem, as soon as possible, that would be of great help.

Cheers,
Joel

Hi Joel,

you updated to the latest development version, not to the stable version 3.6.0. This error has a patch waiting to be pushed:

Betreff: [Koha] Help Please! Problem during upgrade to 3.06.00.001

Hi All,

Please help!

I’ve just upgraded my virtual box (Koha running on Debian, virtual machine
created by Kyle Hall), and now encounter this error when navigating to the
Staff Client in either Safari or Firefox. How can I overcome this?

Software error:
Can't call method "cookie" on an undefined value at
/home/koha/kohaclone/C4/Templates.pm line 323.
For help, please send mail to the webmaster (webmaster@koha), giving this
error message and the time and date of the error.

Kindest Regards,
Joel
