The ZC 155 installer reports PHP 5.5 or newer is required for PCI compliancy.

The server which I have ZC 1.54 running on has PHP 5.4.26 enabled. When I change to PHP 5.5 (within cpanel), ZC 1.54 no longer works (shows blank admin pages). Switching back to PHP 5.4.26, ZC 1.54 works correctly again.

I wish to test ZC 1.55 on PHP 5.5, while ZC 1.54 is still operating for the general public.

Is there something special I need to do to allow ZC 1.54 to run on PHP 5.5 ?

And specific PHP 5.5 libraries I need to enable within cpanel?

Unfortunately phpinfo() is disabled on the server so I'm unable to access the list of PHP libraries currently enabled under PHP 5.4.26.

Thanks,
Woody
