Anyone have any help full advice on how to actually fix this pathway problem rather than telling me to go read pages and pages of documentation?
That depends on wether or not you actually attempted the directions listed in documentation.
Did you remove the cache line from your WP-config file? Did you manually remove the files? Did you delete the .htaccess lines?
I don't see anywhere when you've told us what you DID do (except for installing W3TC, and call me names, thanks for that, way to win friends and influence people). So let's scrap the attitude we perceive from each other.
Hi, I'm helpful volunteer Ipstenu. What HAVE you done to attempt to uninstall WPSC? I would suggest removing all caching tools for a moment, until you have fully uninstalled, and THEN go back and install whichever tool you want.
