Have you double checked your permissions?

Rich

Where do we give the permissions?

The file permissions, if you haven't set them correctly then you'll get errors for sure:

Do you have direct access to your server?

I have given full permissions for the files. However, I tried to do a permissions check (http://our.umbraco.org/wiki/reference/files-and-folders/permissions/perform-permissions-check) and got the following error mesage. I have no idea what the error is about :(..., 

Yes, I have direct access to my server.

Thank you

Hi Anthony

Do you have access to the database. If you do, could you try checking if you have more than one template with the same alias as the one you are trying to save?

/Kim A

        public string ListTemplate()
        {
            string templateList = "";
           List < Template> tt = Template.GetAllAsList();
            foreach( var t in tt)
            {
                templateList += t.Alias + "<br />";
            }
            return templateList;
        }

try and see if you can find any duplicate template alias.

Remember to add

using umbraco.cms.businesslogic.template;

Any solution/updates for this issue....please update. I get the same message. I have just one template with the alias and the permissions look good too.

--update ...................it was permission issue....giving permission to the root folder for the Network Service solved the problem.

Thanks.

is working on a reply...
