Can't confirm, Error Reporting is set on Maximum, also tested on Development

@franz-wohlkoenig Make sure you don't select a Menu in Select Menu dropdown, see this screenshot

Select Menu Items, no Error shown:

@franz-wohlkoenig At the right, there is a a dropdown Sort Table By. Select Ordering ascending and you should see the notice

Changed ordering in Sort Table By:, no Notice.

Don't know why you don't see this error :(

Tried Safari instead Firefox, same Result. But other see Notice, PR works, all fine.

I also tried, can't confirm

That's so strange to me. Could you please:

1. Try to check it using a nightly build installation https://developer.joomla.org/nightly-builds.html

2. Access to Menus -> All Menu Items (the URL looks like this http://localhost/cms40/administrator/index.php?option=com_menus&view=items&menutype=)

3. In the Sort Table By dropdown, set it to Ordering ascending

(See this screenshot, the selected value of the two dropdowns is important)

@joomdonation, done like you wrote, same Result (no Notice):

Final try: Go to System -> Global Configuration, look at Server tab, set the config option Error Reporting to Maximum, then try again

If still no notices, I don't have any other clues

"Error Reporting" is set on Maximum or on Development: No Notice.

Strange. I can see the error, both from the test and from reading the source code. We will have to wait for others to test it, then

i tried also with branch https://github.com/zero-24/joomla-cms/archive/indexphp-40.zip – no Notice. Wait on other Testers.

I'll try reinstalling J4 later on.

$saveOrderingUrl is only defined if both $saveOrder and $menuType evaluate to true, but is only used if $saveOrder is true. Just on reading the code, @joomdonation instructions are correct for reproducing the error. If nothing else, it shows there's a logic error in the layout.
