I am using Sitecore 7.1, created a new campaign in Marketing center, but after saving when i try to open it, it gives the error An error occurred while loading report data. Please try again or contact your administrator.

Same happens with Engagement plans, i get this error when i try to open it Error Loading Engagement Plan.

Answer 1

Try clearing the browser cache and restart browser, this usually helps.

Also. You need to approve the campaign through the workflow before publishing. And off course, make sure you have Sitecore DMS installed :-)
