Magento upgrade 1.7 caused following error

Admin panel works fine, but on front-end I get following error.

SQLSTATE[23000]: Integrity constraint violation: 1052 Column 'position' in order clause is ambiguous

Any idea what could this be?

Here is the solution i came up with, Many Thanks to Vern Burton.

Located table eav_attribute in phpmyadmin, which was related to catalog_eav_attribute.
Located column position in table eav_attribute and dropped it.
Cleared all cache and reindexed all data, visited front page and got a new error: SQLSTATE[42S22]: Column not found: 1054 Unknown column ‘main_table.include_in_menu’ in ‘where clause’
Located and opened file app/code/core/Mage/Catalog/Model/Resource/Category/Flat.php

Commented out following line:267 in my case ----

    ->where('main_table.is_active = ?', '1')
   // ->where('main_table.include_in_menu = ?', '1') 
    ->order('main_table.position');

I'm not really sure how esthetic this method is to fix this issue but, certainly works for me for now, If anyone has better way of fixing this I'd appreciate if you'll post your solution.

Hope this will help someone out, Cheers.
