Error Loading Survey: You have not been given permissions to complete the survey
If you have created a SharePoint survey and users are receiving an “Error loading survey” message or “You have not been given permissions to complete the survey” message when trying to access and complete the survey as shown below:

You can solve this by ensuring that all users (that are required to complete the survey) have Contribute permissions on the site and library that contains the survey.
