I recently starting getting the following error on my site and in my post management area.
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 category_nicename FROM wp_categories WHERE cat_ID=
I am seeing no other errors so far.
I diabled all the plugins. Still there.
I changed my permalink status:
/index.php/category/ [I tried w/o trailing slash]
I got into this pickle after deleting a category.
If the suggestion is to reinstall, can I still keep my data? Sorry for such newbie questions....
