Problem with maps editing in Zabbix 1.8.5

[alvaroarb]

Hi to all
I'm having a strange issue when i try to edit or create maps in a freshly installed Zabbix 1.8.5 (from source code), i can't see the grid that usually displays so i can place objects, i can add icons but they remain in a small horizontal space and i see this message
"a session had already been started - ignoring session_start()[/sur/local/share/zabbix/imgstore.php:86]"
(attached screenshot, an image is woth a thousand words)
Thanks in advance for any help.

It seems that you have session.auto_start enabled. Try to set it to 0 in php.ini.
