Welcome to the Jamroom forums!

A white screen usually means a PHP error - i.e. your PHP has a missing function or configuration that is causing the error.

Go into your ACP -> Core -> Tools -> Activity Logs and look in the "PHP Error Log" tab - that should tells us the issue.

Hope this helps!

I'm going to guess that the "system" function has been disabled on your server - that's why those functions won't run. Try this - create a new file called "phpinfo.php" with this inside:

<?php
phpinfo();
?>

And upload it your server into your jamroom root directory - then run it from your browser - i.e.

yoursite.com/phpinfo.php

There will be a lot of output, scroll down until you get to the "core" section and look in the "disabled_functions" line and let me know if you have any disabled functions.

Hope this helps!

Go ahead and remove that file - you don't want to make that available everywhere.

The root cause is that you have a list of functions that have been disabled by the "Suhosin" extension on your server:
passthru, show_source, shell_exec, system, pcntl_exec, popen, pclose, proc_open, proc_nice, proc_terminate, proc_get_status, proc_close, leak, apache_child_terminate, posix_kill, posix_mkfifo, posix_setpgid, posix_setsid, posix_setuid, escapeshellcmd, escapeshellarg, exec
The only one of those that Jamroom needs is the "system" function - that will need to be allowed in your suhosin config, then the web server needs to be restarted.

Hope this helps!

I would recommend contacting your hosting provider - it's something they will need change at the server level.

Hope this helps!

Ahh - no worries ;)

I'm not a centos user, but I think you'll find the suhosin config at /etc/php5/conf.d/suhosin.ini - open that up and remove "system" from the disabled functions, then restart apache:

/etc/init.d/httpd restart

Hopefully that is where the config file is - if not, try doing:

locate suhosin | grep ini

and see if anything comes up.

Hope this helps!

Based on this:

http://forums.zpanelcp.com/Thread-Where-s-ZPanel-Suhosin-Config-File

it looks like the config might be at:

/etc/php.d/suhosin.ini

Hope this helps!

I can see the disabled functions in your suhosin, so it has to be defined somewhere - that's not the default. It looks like you are running a server control panel, so look in your server config in your control panel and see if you can spot "PHP Options" or something like that.

Hope this helps!

Be careful with the Zpanel system it has been hacked by many and if you plan on running a professional site id recomend not using the zpanel system. Zpanel is cool however hackers have found an easy way in.. Just thought id pass that along. http://www.h-online.com/security/news/item/zPanel-hacked-after-support-team-member-insults-forum-user-1864795.html
