Hi everyboy!!
thank for your precious support, I can tell you that after a series of tests I see that the problem is in the loops,
I use a specific code to query my DB in order to show specific post in the future:
the following is the first one:
<?php query_posts('showposts=-1&order=ASC&cat=-14,-10'); ?>
<?php if ( have_posts() ) { while ( have_posts() ) : the_post(); ?>
<?php static $ctr = 0;
if ($ctr == "3") { break; }
else { ?>
<?php $mylimit=60*60*24*7; //secondi * minuti * ore [* giorni]
if ((get_the_time('U') < (current_time(timestamp) - (get_settings('gmt_offset') * 3600) + $mylimit)) && (get_the_time('U') > current_time(timestamp)) ) {?>
the following is the second:
<?php query_posts('showposts=-1&offset=2&order=ASC&limit=5&cat=-14,-10') ; ?>
<?php if ( have_posts() ) { while ( have_posts() ) : the_post(); ?>
<?php static $ctr = 0;
if ($ctr == "7") { break; }
else { ?>
<?php $mylimit=60*60*24*7; //secondi * minuti * ore [* giorni]
if ((get_the_time('U') < (current_time(timestamp) - (get_settings('gmt_offset') * 3600) + $mylimit)) && (get_the_time('U') > current_time(timestamp)+48*3600 ) ) {?>
