Anyone else run into an issue where you can no longer apply themes to WSS sites? This has occurred across the board for all WSS sites on our portal. We cannot change from the default theme to any of the themes listed under "Site Settings, Apply Theme To Site." SP appears to accept theme selection but returns to default theme.

If already uses a non-Default theme, the default theme appears regardless of actual theme selected. We can re-apply the original theme.

This applies to portal sites and My Sites.
