even when I go to http://192.168.0.253/zm/cgi-bin/nph-zms it's still blank, although black, not white.

here is the white page when I go to http://192.168.0.253/zm

maybe something with cgi? logs aren't showing much, where should I look to see what the problem is?

[iconnor]

Check /var/log/zm/web_php.log

I assume since you got a blank page you actually did the a2enconf zoneminder.

Normally a blank page means php crashed, and there should be more info in the apache logs, but you posted them and we don't see anything.

[blaczero]

sudo a2enconf zoneminder
Conf zoneminder already enabled

Hey, I have got the same issue after updating Ubuntu Server to 24.04, however my apache error log (/var/log/apache2/error.log) contains the following:

Code: Select all

[php:error] [pid 1042] [client 192.168.1.4:60282] PHP Fatal error:  Uncaught Error: Found unconstructed IntlDateFormatter in /usr/share/zoneminder/www/includes/config.php:168\nStack trace:\n#0 /usr/share/zoneminder/www/includes/config.php(168): IntlDateFormatter->setPattern()\n#1 /usr/share/zoneminder/www/index.php(51): require_once('...')\n#2 {main}\n  thrown in /usr/share/zoneminder/www/includes/config.php on line 168

[iconnor]

sudo apt install php-intl
sudo systemctl reload apache2

[blaczero]

sudo apt install php-intl
sudo systemctl reload apache2

page is still blank after this.

Don't know if this means anything but I can display

http://192.168.0.253/zm/robots.txt in browser
User-agent: *
Disallow: /

and for the heck of it

$ sudo apt list php
Listing... Done

[blaczero]

Getting this in Chromium browser, still blank in firefox

just displaying index.php...

should I try and repair php?

[JDS]

Same here, php-intl is already installed.

[blaczero]

apt install php

working now... problem is i'm on 1.34 from my repository. how do I get to 1.36?

[JDS]

Still no joy on my end. I am running 1.36. Did you install from the PPA? You probably just need to update your software sources then.

[JDS]

I've done some more digging but still haven't been successful in finding a solution. I wonder whether there is an issue with compatibility with PHP 8.3 which ships with Ubuntu Server 24.04.1. I might end up having to reinstall the entire VM.

[JDS]

Having left this for a while, it seems to have fixed itself with an update of some package. All back to normal... pheew, I was dreading having to set this all up again.
