the following code appears at the bottom of my admin page: ob_end_flush(): failed to send buffer of zlib output compression (1) in /home/benemota/public_html/wp-includes/functions.php on line 2619

Line 2619:

function wp_ob_end_flush_all() {
    $levels = ob_get_level();
    for ( $i = 0; $i < $levels; $i++ ) {
        ob_end_flush();
    }
}

I already disabled all plugins to see if there was a problem with one of them, but it continued anyway.

There is another detail, when I click on any plugin, my admin panel remains blank with the error code in the footer
