Thanks very much for the Ultimate SEO URLs contribution. It's exactly what I need for my store.
I cleared my store off the server (backed up first) and installed a clean milestone 2.2 OSC store. I empited the database of all products, customers, etc. No other contributions are installed. The path to the store is /store/catalog/ . I've installed the files and added the code as directed in the install.htm file. I've logged into the admin section and cleared the cache. I called up the store, but I still see the osCsidblahblahblah. I checked a spider simulator and it too logged the sid.
It's true that it's way past my bedtime, but I don't believe I've made mistakes.
Can you please let me know (when you have time) what the best guess is as to what I've done wrong?
Thanks very much,
