Contao Simple Product error after update from 3.5.x to 4.13.x

[luciby]

Don't know what is going wrong. Module Simple Products works in backend, on frontend when I click on product list, I get an error:

Which version of the Extension have you installed?

[luciby]

It is a latest version, 4.9.0. I don't know what that error means. Contao is 4.13.43 and everything runs on XAMPP, Apache/2.4.58 (Win64) OpenSSL/3.1.3 PHP/8.2.12.
Thank you for helping me.

Since this is a commercial extension and we can't take a look into the code: Best option should be to contact Fast & Media directly

Ooops. sorry, I've got this wrong.

If it's an issue with that plugin, they should still contact Fast & Media to get support since he's not being active on the forum or in Slack.
