If your page does not display the expected content, there are a few steps you can take to debug content delivery.
- Check your activity or campaign code carefully. A typo or other error could cause the expected content not to display.
- Use mboxTrace or mboxDebug to troubleshoot the mbox.
Please go through the below troubleshooting doc as well.
Were you using our visual experience composer (the GUI test composer) to setup this test? If so, this could be happening if when setting up your test activity you accidentally modified a div element higher than necessary to make your tested change. If this were true the test version could be serving the "older" content that existed when you were creating the test activity to a bigger area of the page than you expected.
Are you still facing the issue ? . If yes, Please do let us know so that we can further deep dive into the issue.
Thanks & Regards
