file broke after opening within a zend optimize server

I have a client that has zend optimizer and loads files by the zend Encoder. I opened up one of 开发者_如何学Cthe files and reuploaded and everything broke. didnt make any changes.

When I refresh the page, i get a blank page.

I was just curious is there some type of command line i can run to re-encode the file. I tried re-uploading original files by binary. but when I refreshed the page again it displayed the html and php code within the browser.

Blank page probably means that you have a PHP error. Check the web server error logs or enable display_errors in php.ini.
