Hi Ray, your reply got me thinking and so I moved my db tables to a fresh site in DW and everything is working as expected. I was able to create a db connection, open a blank php form page and use the DA Pages wizard. Where would I start to debug the old site? Would it help if I trashed the _mmServerScripts folder on local and remote and replace them with the ones from the new site?
Mind you, I'd used WA scripts on the old site for many years, but haven't tried using the latest extension again until very recently, when I ran into this trouble. Thanks, Art
