I have installed zabbix 1.8.0 rev 9377 (ZABBIX Sources: Pre-1.8.x (stable) 9380 18 Jan, 2010) and when I open Slide Shows (No slides defined), I have get error:

• Undefined variable: screenids[/var/www/vhosts/zabbix/html/include/screens.inc.php:225]
• Undefined variable: screenids[/var/www/vhosts/zabbix/html/include/screens.inc.php:231]
• Invalid argument supplied for foreach()[/var/www/vhosts/zabbix/html/include/screens.inc.php:231]
