Error when installing 1.4.1 ...

[Vanyuan]

Hi there,

I am in the process of installing zabbix 1.4.1. A postgres database and user has been created. Im currently at step 4 of the web installation. (4. Configure DB connection.)

The database connection tests successfully (Ok), but when I click Next, even although it goes tto the next screen (Pre-Installation Summary), if I click Next again, it takes me back to the "Configure DB connection", with the following error displayed in the top section of the screen...

* Cannot modify header information - headers already sent by (output started at /var/www/html/zabbix/include/config.inc.php:21)[/var/www/html/zabbix/include/page_header.php:58]
* Cannot modify header information - headers already sent by (output started at /var/www/html/zabbix/include/config.inc.php:21)[/var/www/html/zabbix/include/config.inc.php:1859]

I have modified the file permissions (777) just to test, but this was to no avail.

Can anyone help please?

Thank You!

I had the same problem with the zabbix on postgres installation. I had to write the config manually. After that , zabbix worked but would often loose the connection to the postgres server, at that point I decided to use mysql which seems to work a lot better and the setup wizard worked without problems.

Rather use mysql, postgres setup unreliable?

Alo there,

Does this mean one cannot use the postgresql setup? Don't know what the use of including it is then if it cannot be used.
