Problem with query_posts

[toniboni88]

When I use the function "query_posts" --> ​http://codex.wordpress.org/Function_Reference/query_posts" before the loop, I see correctly the first posts, but if I click on other pages I look the same articles, even if I go on the last page.

Example:

query_posts( 'cat=1' );

I have the same problem.

​http://codex.wordpress.org/Function_Reference/query_posts#Usage_Note:

The wp_query object will generate a new SQL query using your parameters. When you do this, WordPress ignores the other parameters it receives via the URL (such as page number or category). If you want to preserve that information, you can use the $query_string global variable in the call to query_posts().

Try this:

global $query_string;
query_posts( $query_string . '&cat=1' );
