news.php?id=409' --> You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' ORDER BY datePosted DESC' at line 1

But when i try "union all select" it always says --> The used SELECT statements have a different number of columns!

How i can find the number of columns? (ORDER BY not working properly)

Try

news.php?id=409%20ORDER%20BY%20n%20--%20

and substitute n with a number. Try first n=4 and it this throws an error try n/2, if it doesn't give errors increment n. Using such a method you should be able to find the desired number of columns.

When i said that "ORDER BY" is not working properly I meant that i get always "Unknown column in 'order clause' " (even if n=2)
