I’ve just checked my error log and run debugger and I’m not seeing these notices so not sure how to fix it.

They aren’t errors they are just notices. The latest versions of PHP have got very picky about defining variables before they are called. It doesn’t stop anything working so are just an annoyance.

yes, but with 2.8 version the form doesn’t show up.
I keep you updated.
ty

i’m still on v 2.7
and i’m making some attempts.

settings.php L226
if (!$settings['sort']) $settings['sort']=$default['sort'];
in
if (empty($settings['sort'])) $settings['sort']=$default['sort'];

and, right now, i’m not getting any notice.

Not sure what you mean by the ‘form doesn’t show up’ in V2.8?

I’m using V2.8 on the support site and it’s all good.
