Isn’t that an anti-300 site actually? And I don’t see where it’s modx powered. Please enlighten us.
That lightbox script does not prove that it is MODx; that script exists outside of MODx. Indeed, I use it on a Classic ASP ecommerce site.
If this anti-300 site *is* powered by MODx then they’re doing a very good job of hiding it - /manager doesn’t work, /1.html doesn’t work, and all the image and scripts are referenced from different locations than MODx’s defaults. (No "assets" anywhere.)
Now, this is supposed to be "You and Your Sites", not "Sites You Think Are MODx Powered Because They Share A Visual Effect". I’m moving this accordingly to off-topic.
