Yeh for typos! Should be 'groups'... I hope that's the only issue.

you should really try some unittests :-) Then those bugs wouldn't hit the users :-)

Actually, this is code I haven't touched on a long time, so I'm surprised it's throwing errors. And yah, automated testing is something I keep meaning to learn but never quite get around to. It's actually kinda intimidating.

Maybe just start with some end to end tests that automatically perform some tasks on your site. Have a development instance and have a script that klicks all the links and fills in the forms.

Here are some links:
Codeception
Canoo Webtest

Edit: Wow they seem both very simple.... I will probably start using one of those myself...
Just go small steps. You could write a test for every bug posted and every new feature. Then it won't be much work at once and you will slowly build up a test base that will save you trouble in the future.

Wow again :-) With Codeception and the Quickstart guide you can have a running test in 5 minutes ...

This bug if fixed, and yah, I'll look into getting to unit testing.
