Describe the bug and add attachments

Two people on the forum report the same problem. Their backoffice crashes with the error: _Warning Undefined array key tabssimplify

The error happens during a "getLegacyLayout" function call in a Twig file.

The error is puzzling as the word "tabs_simplify" is not present in the Prestashop code.

The forum posts are: https://www.prestashop.com/forums/topic/1082345-probl%C3%A8me-prestashop-81-warning-undefined-array-key-tabs_simplify/ and https://www.prestashop.com/forums/topic/1082642-oops-please-correct-the-items-below-and-then-click-refresh-information-to-test-the-compatibility-of-your-new-system/?do=findComment&comment=3468757

Hello @musicpanda,

Thanks for reporting this issue! Ping @PrestaShop/prestashop-core-developers : Could someone please try to reproduce the issue, it's too technical!

Thanks in advance!

The issue is probably related to the pseditionbasic module, not the core itself.

Hello @musicpanda we fixed this issue in 8.1.2 version of Prestashop Classic, could you please retry it with this version and tell us if it's ok ?

I can't immediately test it. But I trust that it has been fixed and will close the issue.
