Hello, I used that code (Inside HEADER.TPL)
{if $category->id == XX}<title>MY CUSTOM TITLE FOR THAT CATEGORY</title>{else}<title>{$meta_title|escape:'html':'UTF-8'}</title>{/if}
For use CUSTOM Title in only one special category... It works but all products inside that category gets the title, not the product title... I don't know how can I fix that.
Example: Title in category XX -----> "Special Offers T-Shirts Adidas - MyWebPage"
Title in all products inside that category ---> "Special Offers T-Shirts Adidas - MyWebPage"
That's weird...
