Hi. I have error in module settings section. M.2.4.6.
Undefined array key "id" in /var/www/vendor/magento/module-config/Model/Config/Structure/Element/Iterator.php on line 63

Please add tab id in config section

Hi @max3w
We are verifying the issue. We will update and release new version soon.

Thanks you!

Hi @max3w
I see the problem because you are missing module Lof/All. Please setup the module Lof/All together with ProductReviews module.
