How to fix the 403 error on preview in Umbraco after upgrading

Posted written by Paul Seal on October 03, 2019 Umbraco

I ran into an issue today with a site which had recently been upgraded.

The customer reported that the preview didn't work any more.

I did some googling and I found a thread on Our Umbraco which was marked with a solution, but the solution which actually worked for me was further down.

The solution was to delete the folder

Umbraco > Preview

The reason for this is because in the upgraded version of Umbraco the files have been moved to the new folder:

Umbraco > Views > Preview

So by deleting the old folder it solves the issue.

Thank you to Paul Wright for posting this solution #h5yr
