Did you copy all of your masterpage files to the production server?  Found under /masterpages.

I assume you did this in a package?

How to you mean in a package?

All my masterpages are uploaded and I can view document types, but no templates. This is the error I get when I try to edit a masterpage (with the stack trace above):

Server Error in '/' Application.

---

Object reference not set to an instance of an object.

Did you move the Umbraco database and amend the connection string in the web.config file accordingly?

Hi,

I have a similar issue to Tizer, I've upgraded to 4.5.2 from 4.0.4.2. (running asp.net4 , iis6)

Everything is fine, all pages are there but if I click templates nothing happens, all my templates are missing from 4.0.4.2.

Issue with Doc Types too, I can see them but when I try to preview it, it spits out this error:

Server Error in '/' Application.

Object reference not set to an instance of an object.

I can still see my templates under the /masterpages folder but they don't appear under Templates in Umbraco.

There are no duplicate entries in the DB so I have no idea why this is happening.

If I turn this off: in umbracoSettings.config

  <templates>
    <useAspNetMasterPages>true</useAspNetMasterPages>
  </templates>

I can see all my templates in Umbraco, Doc Types appear and work but if I click on a template it throws a different type of server error :( Anyway I've turned it back on.

Does anyone have any ideas?

Hi there,

we just got across the same (I think) issue. What turned out to be the reason for us was some discrepancy between umbracoNode and cmsTemplate tables, i.e. there were nodes with template type in umbracoNode and that were missing in cmsTemplate. It caused exactly the behaviour of throwing null reference exception while calling 

http://localhost:XXXX/umbraco/webservices/TreeDataService.ashx?rnd=6d8884c0b5db40be9400fbd6c3dfae7a&id=-1&treeType=templates&contextMenu=true&isDialog=false&rnd2=42.3 

and not displaying any nodes under Templates in settings tab.

Easiest way to find out if this is the case, run the following query:

SELECT [pk],[nodeId],[master],[alias],[design],id, trashed, parentID, nodeUser, level, path, sortOrder, uniqueID, text, nodeObjectType, createDate
  FROM [cmsTemplate] t
right join umbracoNode un on t.nodeId = un.id
WHERE un.nodeObjectType='6FBDE604-4178-42CE-A10B-8A2600A2F07D' 

and look for nulls in "left" side.

Hope this helps someone.

What does it mean if all your record in the cmsTemplate Table contains null values for the "master" column?

is working on a reply...
