We have never experienced this issue in Umbraco 4, but we've got this twice in Umbraco 7.
The Problem
So we've got a page: www.mywebsite.com/sale
It has been working for a month, then suddenly it shows 404:
The (non-ideal) Solution
We could change the template of this document, eg. from SalePage to TextPage, then back to SalePage.That will temporarily fix it.
But after IIS restart, or after republishing the page, it will show the 404 error again.
For a permanent fix, we have to change the page name, eg. from Sale to Sale1.
The Question
Sometimes changing the page name is not an ideal solution at all.
Has anyone experienced this? Or know where to look? May be the database has a corrupted entry somewhere..?
