So after I installed some plugins which were necessary for my newly purchased theme, I got this:

WordPress database 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 '' at line 1]
SELECT COUNT(*) AS comment_count FROM wp_comments WHERE comment_approved = 1 AND comment_post_ID =

Warning: Cannot modify header information - headers already sent by (output started at /home2/abhinav/public_html/wp-includes/wp-db.php:1055) in /home2/abhinav/public_html/wp-admin/post.php on line 233

I'm new to this, can anyone help? I don't think it's the whitespaces either and the errors remain even after I deleted the plugins and changed the theme. Site is www.thebottomcorner.com.
