When using Sharepoint Designer 2010 to create custom aspx list forms I was getting the error:
‘sharepoint designer could not save the list changes to the server’
I had a look on the net but couldnt really find anything relating to do with this.
I seem to have solved it by going to my list and removing duplicate column names that werent being used ie.
Consultant #Used in CT ‘Consultant’#
I was using a custom content type so I deleted all the columns that weren’t ‘Used by’ my custom content type. Once I had done this I was them able to create custom forms as expected in SPD 2010.
Hopefully this will help some people if theyre getting similar problems!
