Hello again,
I had hoped that it would take a little longer but unfortunately Dr Google hasn't been able to help.
My form is used to submit multiple sets of data for processing in various ways and in its previous incarnation it used php_self parameter to re-present the form after submit. This does not work and I get a Method not allowed error.
I have tried to see if there are any hints in the browser developer window but haven't been able to spot anything of use.
Any hints will be greatly appreciated either to fix the problem or on suitable trouble-shooting methods.
Regards
Harry
