“The file xxx is corrupted.”

If you get an error such as the file is corrupted it is a very good possibility that your host has ioncube installed through php.ini and it is an older version of the loader file.

To fix this error you will need to contact your host and have them upload the new loader file. This is a small change and they should not have a problem making this change.

Here is documentation from Ioncube's website:

Encoder 6.5 needs Loader version 3.1 or greater as it has new security features that are not known about by the older Loaders. Loaders < 3.0 report newer files as corrupted, which isn't strictly correct but couldn't be avoided. Loader 3.0 would say that a newer Loader was required.
