Hi

I've switched my templates around and have been trying to delete a template that's no longer in use. When doing so I get the following in the Sitefinity error log:

Any thoughts on how I may delete this template?

Thanks

Dear Ruth

a) Make sure that no pages use this tempalte (from what I read you have done so)
b) Create a new page, select another template (the one you usually use) and make sure that you set that as default template.

If I remember correct there was once a problem that when no default template was set then creating a new one would cause troubles.

This is just a 5% to solve your problem but still worth a try.

What version are you using?

Hi Markus

I've followed the steps you provided but get the same error I'm afraid.

So I create a new page assigned a template other than the one I want to delete and marked it as default. I then deleted the new page and attempted to delete the template both on the page templates list screen and also once I had clicked through to the template in question.

We are using the latest version of Sitefinity - 5.1

Any other thoughts?

Thanks

Brin

@Brin

I said it was a long shot - I would open a support ticket. Tomorrow Bulgaria is working with limited forces.
