Hey Core Team,

when I am using the switch user plugin and after switching user gets a warning on the top bar more information you can see the mentioned screenshot.

For more information see mentioned screenshot.

Warning: array_flip() expects parameter 1 to be array, null given in wp-admin/includes/menu.php on line 307

I have checked condition before array_flip

Thanks for creating this ticket @sumitsingh!

If a plugin is filtering the menu order and returning an invalid value, I think it's okay that PHP shows a warning. The plugin author should see this warning and act to resolve the issue.

Adding close and 2nd-opinion.

What role does the user have?

Does this happen if you manually log into the affected user account (using the username and password) instead of switching?

Can you try deactivating your plugins one by one to see if one of them is causing this error?

@johnbillion, I am switching admin to the subscriber user role.
