ispconfig 3 and php 5.2 how?

which solution for to have ispconfig 3 with an OS with php 5.2?

Only solution is the php downgrade ?

isn't there a package preconfigured with ispconfig and this php version?

 

You can do this, but only with ISPConfig 3.0.5 and PHP in FastCGI mode. This should give you the idea: http://www.howtoforge.com/perfect-server-ubuntu-12.10-apache2-bind-dovecot-ispconfig-3-p4
