If you installed Zabbix server with PHP 7.0 or upper version, then you will face this issue after login to the Zabbix dashboard.

For this issue, just open include/func.inc.php with your preferred editor and change some entry. After change it will look like below.

function str2mem($val) {
$val = trim($val);
$last = strtolower(substr($val, -1));

switch ($last) {
case ‘g’:
$val = (int) $val * 1024;
/* falls through */
case ‘m’:
$val = (int) $val * 1024;
/* falls through */
case ‘k’:
$val = (int) $val * 1024;

}

return $val;
}

After this change restart zabbix-server service once.

Thank You
