Hi, i need help with this one.

i'v installed the SEO module v.1.3.5 and then i'm now stuck on this error page.

Code:
1054 Unknown column 'c.parent_id' in 'on clause'
in:
[SELECT c.categories_id as id, c.parent_id, cd.categories_name as cName,
 cd2.categories_name as pName FROM devi_categories c, devi_categories_description cd
 LEFT JOIN devi_categories_description cd2 ON c.parent_id=cd2.categories_id AND 
cd2.language_id='1' WHERE c.categories_id=cd.categories_id AND 
cd.language_id='1']
Seems like it is looking for the c.parent_id column in the database.
So i went there to look for it, in the categories table and it is there. (Actually there is a "parent_id" column)

So i need some assistance here.

i'd wish to give more infos but i guess that's all i can say.

Thanx for helping me out.
