I am in the process of creating a project management system, in which there is a Gantt chart of all the tasks, displayed as a view of a particular list. I am attempting to save the site as a template so that a copy of the site can be used for each project created, therefore creating a project management 'site' for each project.

To do this I save the template and include all the data (so it includes the lists etc). When I then create a site from the template, the embedded list web parts work perfectly, but in Gantt view I get the following error:

List does not exist. The page you selected contains a list that does not exist. It may have been deleted by another user.

Any help would be very much appreciated!

Hi,

As I understand, you get the error when saving site as template in SharePoint 2013.

You could check things below:

1. Check the details about the error in the ULS log.

2. Open the task list in the SharePoint designer, get the listid in the list information section. Then you open the gantt chart view in the designer, search the ListId, then check if the two listids are the same as the pictures below.

3. Delete the web part and re-add to check if it can work.

Best regards,

Sa
