De.scription and Message

I recently switched hosts and everything seems to be working just like it should. But, when I tried to upload a KB article the next error appears:

[align=center:3dyqdkq1]Could not update category data

DEBUG MODE

SQL Error : 1064 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 'WHERE category_id = ''' at line 1

UPDATE phpbb_kb_categories SET number_articles = WHERE category_id = ''

Line : 337
File : functions_kb.php[/align:3dyqdkq1]

What should I do to fix this? Thanks!
