I have used this mod without a single issue for YEARS!!! I haven't done a single server wise, or uploaded any new plugin's or mods. Today I got a weird error:

Database error in vBulletin 3.8.5:

Invalid SQL:
SELECT * FROM post_thanks AS post_thanks INNER JOIN user AS user USING (userid) WHERE post_thanks.postid IN () ORDER BY post_thanks.username ASC;

MySQL Error : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') ORDER BY post_thanks.username ASC' at line 1

Thoughts? It's not affecting anything. This error was generated by a FEW ips only. After looking into the IP's it appears that they all are associated with ONE ISP. I'm not sure if this is something wrong...and needs to be addressed (our forum is running just fine) or if we need to look into it and fix whatever appears to be broken! Thanks for the feedback, I LOVE THIS Hack!!
