Help Please - Broke My Site Search

Hi,

Was wondering if anyone can help me. I installed this add on on my site:- http://www.zen-cart.com/index.php?main_page=product_contrib_info&products_id=1173 and it caused error message after install.

So I reversed the install and removed the files added and replaced the one file that was overwritten. The AddOn didn't make any changes to the database but after doing all this I still get the same error message when I use my sites search:-

Advanced Search
1109 Unknown table 'p' in field list
in:
[select count(p.products_id) as total ]

I looked through the install file again and have removed all extra code added but error message still shows so I restored my backup and my database but the same error still shows when you use search.

Can anyone offer any advise on this please?

Thanks

John

Never mind - I fixed by uploading header_php.php again. Must not have worked first time round and found this solution via Google.
