I have a Drupal 8.7 site with a content type for which I have just activated automatic URLs via pathauto.
We have a number of pages using this content type, and all of them worked perfectly when I activated the alias... except for one, which remained stuck as
I investigated this, and it turned out that the content editor who created the page had unticked the 'Generate automatic URL alias' checkbox on this particular page, hence why it didn't pick up the new pathauto alias.
So I thought it would be a simple thing to tick the box and it would work.
I ticked the checkbox and saved the page, but what actually happened is that it now gives me a browser error saying "page isn't redirecting properly" (Firefox) or "too many redirects" (Chrome).
I have tried regenerating the aliases, manually changing the alias, deleting the alias, recreating it... but nothing I do is getting the page back.
My guess is that there's something that's gotten saved in the pathauto database tables for this which is broken, but isn't showing up in the admin panel.
Can anyone please help me understand what's going on under the hood here and fix this alias.
