We are trying to implement a custom list in SP 2013 hosted version. The custom list template was built in Office 365 and it will not allow me to access the list or make any modifications. I continue to get the same error message stating it is unsafe and cannot be displayed. I’ve researched the error message and haven’t really seen any feedback for my issue. I have the screenshot below. If anyone can point me in the right direction it would be greatly appreciated.

@Ellya Gold could you provide some guidance on how to add a new item to the list? Or utilize the list as a template?  Are you familiar with this  Correlation ID: 04ccb39d-6642-009d-ac01-1cedb84ed0fa?
If you want to close the web part so you can access the page again, add ?contents=1 to the url of the page to go to the web part maintenance page.
example:
http://sharepoint/sites/Home.aspx?contents=1
