Setup/first run, blank page, no errors in logs

[s2390]

Hi

Ubuntu 14.04.3 LTS
PHP 5.5.9

I've just installed Zabbix but all I get is a blank page.

/var/log/apache2/error.log has nothing in it.

/var/log/apache2/access.log just shows:

1.2.3.4 - - [09/Sep/2015:17:11:32 +0000] "GET /zabbix/ HTTP/1.1" 500 379

I have put a test file in the Zabbix dir with a simple PHP echo statement, and that works. So PHP is all working fine in /usr/share/zabbix/

Folder and files are owned by www-data

Any ideas please?

So I tried adding to the top of index.php the following to see if it showed any errors:

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

Still blank in the browser. Still no errors in error.log but interestingly... access.log now show a 200 rather than a 500.

Solved!

I didn't have php5-mysql install. D'oh.
