error in SQL syntax help

[chubbymshippo]

Hi guys,

I'm new to this forum and Prestashop, but I've been scouring the forums and couldn't seem to find a solution.

When editing the CMS and infoblock for my webpage, it seems that as soon as I delete the "about us" and "terms and conditions" pages a major error comes up for me. On my webpage, the right column disappears and a code error appears on the bottom of the screen:

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 4

SELECT c.id_cms, cl.link_rewrite, cl.meta_title
FROM ps_cms c
LEFT JOIN ps_cms_lang cl ON (c.id_cms = cl.id_cms AND cl.id_lang = 1)
WHERE c.id_cms IN ()

Does anyone know how to fix this?
