Upgrade to 4.x

Hi,

Despite me telling the bossman that it's not production ready, he's gone ahead and okayed a project running OC4.

Is there a 'best version' to upgrade from? I have a 2.1.0.1 version of the store and a dev test version that's currently on 3.0.3.8 that I'd love to leave it on for now, but a test upgrade from 3.0.3.8 to 4.0.2.0 has left me with the following error that I have no idea how to resolve:
PHP Version is 8.1.17.

Should I upgrade directly from a specific version for best results? I had a brief look over github and couldn't find anything similar - any help with this one would be massively appreciated!

There's no reason to upgrade to OpenCart 4.0 if you're on 3.0.3.8. I would advise against it, since it will cost many hours in fixing bugs and updating all your extensions.

If your boss insists, then you should wait a few weeks if possible, until a stable 4.0.2.x version happens. If you can't wait that long, at least wait a few days to see if more releases happen in the near future.

Exactly what I've been telling him but no luck!

I've solved the issue, by modifying the file install/controller/common/column_left.php on line 2 with
Setup worked fine with this change. Where should I report other issues that I encounter - is here best or the should I head over to github?

Just delete column_left then refresh

Github is better to report issues. The forum is more for community members, where we can discuss fixes, but I don't think Daniel checks it for bugs any more. (He used to originally, before he moved to github a long time ago.)

Also ensure to post OC 4 bugs, not below, on Github in the opencart/opencart repository.
