I worked in wordpress created on pagination but always first page the same as current page
so solution is :
$pag_args1 = array(
'base' => @add_query_arg('paged1','%#%'),
'format' => '?paged1=%#%',
'current' => $paged1,
'total' => $query1->max_num_pages
);
this case we attention must and base =>..... because par defaut first page not add parametre !!!
