Hi and welcome to Trac!

If you want site support, the support forums would be a better place to ask:

However, I'll leave this ticket open for now. The undefined key is the user capability needed to display a sub-menu item in the side admin menu, and maybe the condition needs to check whether the key is set/non-empty before using current_user_can().

Check for non-empty array key 1 before using it with current_user_can() to avoid PHP warning

Adding needs-unit-tests since some were requested in the PR.
