When logging into the OnBrand portal you could receive a blank screen or an "Oops...This dashboard may have been moved or deleted. Contact your administrator for help." or perhaps you can log in but cannot access the instances you have access to. This article describes a solution for this issue.
From previous tickets, we have seen some cross-site scripting when the target domain is different from the source domain creating issues when accessing the OnBrand portal from another application, like a CMS (content management system).
In many cases, you can add the
target=”_blank” attribute to your anchor in your CMS if you do not have access to the HTML code. You should also add
rel="noopener" to every
target="_blank" link to avoid a security issue. If you have access to the HTML code, this should be fixed there by one of your developers.
