Child document redirects to parent

Check to see if you have a page alias in either of the pages. You can find this under the Page Properties>URLs>Page aliases

Also if you have any Redirect modules installed in Kentico, check that too.

I've deleted all the aliases from parent and child and still the same. There are no Redirect modules installed, just default ones.

While checking options, I came to the following: If I go to Document -> Template -> Inherit Content -> Select inherited levels and check all except root level it will not redirect, but it won't show the layout of the page either, just the document's html.

Is the /Collections/Exhibitor-list/XXXXXX.aspx page actually in the content tree or is it a dynamically created page, meaning there is an alias or URL parameter to display the XXXXXX exhibitor? You might also check the Properties>Navigation tab for that XXXXXX exhibitor, it might have a redirect set on it already.

The exhibitor page exists and it has a path assigned to it: Alias path: /Collections/Exhibitor-list/10-IS Culture: English - United Kingdom Name path: /Collections/Exhibitor list/10 IS Live URL: /Collections/Exhibitor-list/10-IS.aspx Published: Yes

Navigation -> Menu action is set to Standard behavior

Another clue I discovered while testing: When moving the Exhibitor elsewhere it still redirects to the parent document, even if the parent document is different from exhibitor-list. But it won't redirect if the exhibitor is placed as a direct child of the tree root.

Then there must be something attached to that page, you might check the page template or the content on the page to see that there isn't any kind of javascript doing the redirect.
