We are running 10.0, our dev store has a fully working /bestsellers page, but production server fails to load and after some time goes to the 404 error. I have done a diff check across all code files on dev and production they are all identical save a few very minor differences in comments. The database doesnt seem to be a factor either as i took the production DB and moved it to the dev server and it was still able to work. I am not sure what could be going on here but i suspect an IIS difference but i have not been able to identify any obvious issues here either... Does anyone have any idea what might be going on here?
