I wont do anything to live site but to test first . Now in test site i created a second folder with invision files but when i changed the folder name show that need to make installation first again .... and ask also for a license key that is already be used with the other folder in first place installation . Can use test key for second time for the same domain but for a test folder ?
I am testing if can create a second folder and just change the name ( rename existing to something else and new with the existing name ) in order to minimize the risk .
Many thanks
