PHP Multiple versions

the error.log shows this:

[Wed Jun 05 01:39:28 2013] [warn] [client xxx.xxx.xxx.xxx] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
[Wed Jun 05 01:39:28 2013] [error] [client xxx.xxx.xxx.xxx] Premature end of script headers: index.php

I changed the bin path to /opt/phpfarm/inst/bin/php-cgi-5.2.17 (this looks better?)
and I can't find any other php.ini other than /opt/phpfarm/inst/php-5.2.17/lib/php.ini

I would appreciate any suggestion as i'm not sure which is wrong, the paths or something on the website, although I migrated it from a debian lenny which means it was using php 5.2.17, right?

 

Any luck solving this problem?

I installed Ispconfig 3.0.5.3 with PHP 5.3 and wanted to add PHP 5.2 support, everything went fine, but I also got erro 500...

[EDIT] Ok, I needed to uncomment:

Code:

Unix user of processes
                <value name="user">nobody</value>

                        Unix group of processes
                <value name="group">nogroup</value>

in /opt/php-5.2.17/etc/php-fpm.conf

Now 5.2 works fine!
