the problem is the URL Prefix on the testing server, but i would like to back up to the local info tab first.
if you are going to place the testing server files in:
it does not make sense to put the local info files in:
all this does is create duplicates of the files on your system.
I set the local info and testing server tabs to use the same location, the remote tab is only needed when you uplaod to an external remote server.
now, onto the error:
maps to the C:\xampp\htdocs\ folder on your system
where you are creating the site in a subfolder:
the url prefix on the testing server tab needs to include that subfolder:
you should also use that address for the HTTP address on the local info tab.
