Product name disappeared

[Guest]

Hi All,

 

I wasn't sure where to post this, so I thought here might be a good start :)

 

I've installed the Simple Template System contribution and the Header Tag Controller contribution ... All appears to be working fine, although the Product Name option in the admin/catalog/add new product has disappeared!!

 

Has this happened to anyone else? Does anyone know in what file the Product Name is in?

 

Any help would be greatly appreciated....

 

Thanks very much!
