Hi Mark,

Unless the site is using the Zend Optimizer, PHP files are generally not compiled. The Zend Optimizer compiles and encrypt PHP files, which improves performance, but also prevents them from being edited.

If you can open the PHP files (say with Notepad) and see un-encrypted PHP code, then the Zend Optimizer is not being used, and you can use pretty much any editor to modify the code.

If this is the case, sounds like a code problem in the update that is causing the page to no longer work.
