Adam I might be wrong but I thought that when you are using the MetaWeblog API that there is actually a limitation as to how many fields can be used. I don’t think it is an ExpressionEngine limitation though rather a limitation of the API.
I definitely stand to be corrected on this though as I swear I read this somewhere but now I can’t find the link and it is 1:30 here in the morning so I really should get to bed and couldn’t find the API documentation on the net either. I think I have probably maxed out my Google searches allowance for the day!! 😊
I think I should give in.
If I am wrong though then I would add my voice to that request so please let me be wrong?
Best wishes,
Mark
