Strange situation here. We have a Tab in Salesforce Classic that users click to access a set of Skuid pages. I have one user who has been accessing these pages successfully for months now. Today, he clicks the Tab and only gets a blank screen. No one else in the same profile is having this issue. I verified that he still has the Skuid Page Viewer permission set. I have tried removing and re-adding this, but no change. Any ideas on what might be causing this behavior?
