Just to add after updating the code these errors show

PHP Warning: mysqli_fetch_assoc() expects exactly 1 parameter, 2 given in ... includes/admin.inc.php on line 1189

PHP Warning: Invalid argument supplied for foreach() in ... admin.inc.php on line 1222

I'm sorry, my example code in the former posting was broken (I corrected it meanwhile). Change …

while ($line = mysqli_fetch_assoc($connid, $rGetSettingsEdit)) {

… to …

while ($line = mysqli_fetch_assoc($rGetSettingsEdit)) {

… on both places (settings section and advanced settings section).

And there is a further code change. Go to functions.inc.php, line 93 and change it from …

 if ($current_time > intval($nda[0]['value'])) {

… to …

 if ($current_time > intval($nda['value'])) {

That should solve Juanma's issue with the undefined offset.

Tschö, Auge
