When I install SilverStripe on several places, I always delete installation files after installing (using the delete link in the final screen of installation process). But, for some places, after deleting, browsing to home page (e.g. domain/home/) I get redirected to:
and "file not found" message. Browsing to other pages is OK.
Have anyone experienced this? I don't know why it only happen occasionally, not always.
