JUST TELL-ME: I KNOW WHAT THE PROBLEM IS AND IF YOU GIVE-ME THE JOB, I WILL COMPLETE THIS IN 10 MINUTES! There is a piece of code that I want to use but pagination is not working correctly. This is the code I'm using ( [login to view URL] ) to paginate subcategory links but I'm facing two problems: The first problem This creates a duplicate content issue by paginating two times the first page with different urls; ([login to view URL]) ([login to view URL]) When someone returns to the first page, it should be removing the "?cpage=1" variable... (Last, but not least...) The second problem I would like to know if there is a way to rewrite the URL so that instead of showing; -> [login to view URL](page_number) it show's the url this way: -> [login to view URL](page_number)/
