I am using ubuntu 12.04 ,I could not find php file,there is not misc/php directory in my screen-scraper folder.please can you tell me where I can get remote.scraping_session.php file.

I don't know what could have

I don't know what could have happened. What version of screen-scraper do you have? Is there a misc sub-directory, and if yes, what's in it?

If needed I can email it to you.
