That dreaded provider (GoDaddy)
Hi Jason, I contacted GD and as everyone else reports, they state they have tested their server, everything is OK and they do not overide any ASP settings, it must be a problem with the script and as it is custom, they don't provide support on this issue !
So, I have moved my page to another domain/host(Earthlink) and constructed a test PHP page (As my account does not support ASP).
I tested it once and it worked, so now I will ask my clients around the globe to test it.
Watch this space for further news. If you do have any ideas on the ASP based problems, let me know, as I'd prefer to keep things the way they are, rather than port to PHP on a different host.
