Hi, I'm working on a Joomla site composed by

- Joomla 1.5.10
- VM 1.1.3 stable
- JoomFish 2.0.4
- JoomSEF 3.8.2
- VM JoomSEF plugin 2.0.34
- hwdVideoShare JoomSEF plugin 2.1.2

My customer has just bought both VM JoomSEF plugin and hwdVideoShare JoomSEF plugin yesterday so he ask to me to configure JoomSEF in order to enable SEF on Joomla but when I enable JoomSEF site stop working and show in the head of the page a lot of query errors like:

field 166item_id not found in query SELECT vm_product ...... WHERE ......itemid_166

and url are traducted like www.site.com/it/page.html but when i click on link browser show me a 404 error and tell "404 error - page www.site.com/it,gif/page.html non found".

Help please! :(
