After some research I found solution to paging my content with ajax (php mysql). I have one index which include paging.php and this is ok, but after adding second paging2.php file after clicking on more news content apears on block which is reserved for second paging content.
Here is page where you can see this

Notice that first and second paging file works perfectly
separately.

Any idea ?
