This worked for me:
Deleted singel.php.
copied singel.php from default theme.
in theme editor i deleted all content of the singel.php and copied in my own singel.php code.
Don’t know why, but it works.
Have the same problem. WP just won’t recognize the singel.php page. Have the latest version of WP, 2.8.5.
Tried with multiple, and different singel.php files, but nothing seem to work.
WP uses index for singel post no matter what I do.
Any suggestions out there?
