GoDaddy works fine but imho is getting a bit expensive -
- so I've tried BigRock: I tried everything I could think of without success, then raised a support ticket. Within a few minutes they replied to say that by default their asp.net trust level** is locked at Medium, but they changed mine to High (with the proviso
that they would change it back if any security problems were found).
All now AOK so full marks to them.
(** confusingly there is another 'trust level' setting on their Plesk console).
With a bit of messing about I've also transferred the demo to localhost on Win10+IIS 10 Express, but try as I might I can't get bog standard asp (Classic) to work on that setup (Handler "ASPClassic" has a bad module "IsapiModule"
in its module list) - suggestions welcome.
