>> error with Zlib compression

Good morning,

I get this recurrent error :

Notice: ob_end_flush(): failed to send buffer of zlib output compression (1) in /var/www/vhosts/comme1marque.com/httpdocs/wp-includes/functions.php on line 3719

//

Then I take a look at this line #3719 and find wp function :

function wp_ob_end_flush_all() {

$levels = ob_get_level();

for ($i=0; $i<$levels; $i++)

ob_end_flush();

}

How can I solve this ?

Thank you
