 * This morning I tried to log in to my admin panel and I got this error:
 * WordPress database error: [Illegal mix of collations (latin1_swedish_ci,IMPLICIT)
   and (utf8_general_ci,COERCIBLE) for operation ‘=’]
    SELECT ID FROM wp_users WHERE
   user_login = ‘Åse’
 * I couldn’t log in so I changed my login name from Åse to admin in php my admin
   and I got in. However, my whole blog that uses ISO-8859-1 looked totally weird!!!
   All my Å,Ä and Ös were all messed up.
    I have tried reuploading my sv_SE.mo but
   stilled messed up. When changing to UTF-8 in wp-admin my posts turns up fine 
   again.
 * Is there a problem with my SQL and how do I fix it?
    Thank you!
