Encoded file filename.php expired or corrupt error.

SYMPTOMS
The encoded file filename.php has expired or is corrupt.

SOLUTION
This happens when one of the ionCube encoded files have not been uploaded in binary mode or have been tampered with.

The files are encoded on the fly when you click on the download button and your user information is written to the comments of the php file so is a file checksum, if the file is edited or tampered with in any way it becomes corrupt, same with uploading it in ASCII mode, it changes checksums because of the difference in uploading.

The resolution would be to try uploading the file again in binary mode, if that does not work I would suggest re-downloading the entire system from our members area and re-uploading it in binary mode.
