404 errors still present
The files I had on the server did not have the line you wanted changes.
I moved the two files from the /install/webassist/plugins/catalog director from the 4.0.1 upgrade file the two files that needed to be changed and made the change. It did not seem to work. I also did clear the cache.
See www.glamourup.com >Products > Select All - this will give you the error. So will going to any of the sub-menus under Products
