Hi all, this is my first time posting anything so I must say thanks to all involved with the system. It is really a great product you have here.
I have installed a couple of instances of ErpNext on different machines but have never come up with this error, however today I installed a new ErpNext instance on a machine with another instance running, everything went well enough except on the new installtion whenever I try to create a Sales or Purchase Invoice I get this error.
AttributeError: ‘NoneType’ object has no attribute ‘fieldtype’.
Here is the full errror:
