Server is
WHM 11.23.2 cPanel 11.23.6-R27698
CENTOS Enterprise 4.7 i686 on standard - WHM X v3.1.0

I moved a customer's 3 sites to the above server. He uses a script which requires the Source Guardian loaders.

Here is the error in his admin panels:

<path to file> is protected by SourceGuardian and requires file ixed.5.2.5.lin or ixed.5.2.lin

I uploaded ixed.5.2.lin into his directory that has the loaders, and that didn't fix it.

So I uploaded Source Guardian's "howto-install.php" and it says this:

How to install SourceGuardian loaders
Server-wide setup

1. Download ixed4.lin.x86-32.tar.gz (for Intel x86 32-bit processor) or ixed4.lin.x86-64.tar.gz (for Intel x86 64-bit processor)
2. Extract it to folder /usr/local/lib/php/extensions/no-debug-non-zts-20060613
3. Edit PHP.INI file (located at /usr/local/lib/php.ini) and add following line:
extension=ixed.5.2.lin

So I did that. But maybe I didn't edit php.ini correctly? I added the line extension=ixed.5.2.lin after Zend, at the very end of the file.

But the scripts are still broken.

Is there something I'm overlooking?
