I'm trying to test WHMCS out on a local Windows XP Pro server (IIS5), ionCube has been loaded successfully, I get past the License Agreement step but the next step is a blank page:
http://localhost/whmcs/install/install.php?step=2
It is not a completely blank page, the WHMCS header/logo is displayed and the heading "INSTALL/UPGRADE WHMCS" but then the rest of the page is blank.
Any ideas what the problem may be? Is there an error log I can check somewhere?
