When I load the visual editor my old test information loads, how do I restart from scratch?

When you go to test a page Zentester automatically loads any previous running or paused tests for that page. It does this so you don't accidently create multiple test on the same page that could conflict with each other.

If you wish to create a new test from scratch simply change your old test to stopped. Stopping a test will allow you to create a new test from scratch and will also preserve all the data and settings for the old test so you can refer to them again in the future. Another alternative is to delete it completely however deleting the old test completely will remove all data and configuration for the test permanently.
