I am using Powerview in Sharepoint 2013. We have done a very nice powerview and gave the link to an end user over e-mail without giving the user permission. So he couldn't see the see the Powerview. After that our Gallery Screen doesn't work on the Powerpivot Gallery. We have been getting a blankscreen. So if we upload a new spreadsheet we can't press the create powerview button. So can you guys please help me fix this ? So that we can create a new powerview and get the gallery view back? Thank you in advance
We had a similar issue, you need to make sure that along with PowerPivot for SharePoint you install Reporting Services for SharePoint. After that you can activate the PowerPivot Feature.
