I have created a profile which includes traffic from a single IP address (mine). The reports for this profile doesn’t show some pages regularly. The same pages are tracked on other profiles of the same web site. What could be the reasons for this error? Could it have anything to do with the cache ?

Page caching will not prevent the Google Analytics code from firing. After the initial download, the urchin.js file is cached as well. This is to improve performance for the end user.

In this situation, there are only two things that would cause Google Analytics to not track your visit to the page. 1) A failure with the javascript loading. Make sure it has been added to the page correctly, and you have javascript enabled in your browser. 2) Something is wrong with the filter. It may be the filter was setup incorrectly, or your IP is dynamic, meaning your IP changes from time to time, which would then make your filter irrelevant.

If you are visiting the page and your IP address does not change and the javascript fires, there shouldn't be any discrepancy in the data.
