UBB.threads PHP Forum Software Community Forums UBB.threads Importer Support Redirect scripts not working

I just successfully installed ver 7.1.1 and imported from 6.5.4

Everything went very smoothly, thankfully!

The only problem I have is that after changing the URL in the redirect scripts and uploading them to the old (6.5.4) directory, nothing happens when I go to the old forum: no redirect to the new directory. What am I doing wrong?

Thanks in advance for your help!
