Hi
which version of CAI are you using?
What do you mean by “view” the page? Do you mean that you published the page and then accessed it as described in the documentation (…/servlet/StartCISPage?PAGEURL…)?
Have you tried to clean the cache of your IE and view the page afterwards?
Please do not forget to publish your page inside Layout Editor prior to viewing it outside the Layout Editor. (“Publish” is right from “Preview” icon).
