[wp-testers] Database error message

[Craig]

In the WRITE panel in the CUSTOM FIELDS section I see this error:

WordPress database error: [Error writing file '/tmp/MYTYOtpO' (Errcode: 28)]
SELECT meta_key FROM wp_postmeta GROUP BY meta_key ORDER BY meta_id
DESC LIMIT 10

I have no clue about this one. AFAIK, I don't have any custom fields set at all.

Craig.
