"Please make sure that you do not have 2 templates with the same alias" when I was trying to save a template. I looked in the SQL database under dbo.cmsTemplate and found that there was an item which had a duplicate name. I deleted that row from the database thinking that I would solve the problem, but I have made things worse. Now, when I try to access the templates through Umbraco I don't see any nodes beneath templates. If I try to create a new one, I get the following error:
Object reference not set to an instance of an object.

the execution of the current web request. Please review the stack trace

If anyone knows how I can fix this, I would really appreciate it. Thanks for your help!
Make mistake in SQL Database

Hi Andrew,
There are a couple of other tables that you'll need to remove the template from reference: "cmsTemplate" and "umbracoNode".
Check the "umbracoNode" table first, make a note of the NodeId ... and then delete the related row from "cmsTemplate".
I wouldn't usually recommend that you try to manipulate data directly in the database, but I think you're already in a tight-spot!?
Cheers, Lee.
