Optimizely script not recognized
Anyone has any idea why on this page http://www-05preview.ibm.com/services/europe/fashi
Well the link you posted doesn't work at all, as it seems to be a preview URL of the page you're working on from your internal CMS. So for that it's hard to answer, when I try removing the preview part from the URL and going to the actual IBM site I also don't see the script implemented at all and it also doesn't look like you're using a TMS to implement it with. So are you sure the script is on the actual page?
On the preview page it is. On the live on it isn't. I was just doing some sort of Q&A, tryining to figure out if the script is ok, so i can tell my dev team here to push the page live. I'll do so anyway, and test after.
