I have added a field to the ad form so i have the following

name
message
image
url

however once this has been saved i can't see the message on the ad all i have is

name
url
image

is there something i need to change to display the message?

I just added in a name and then a message fields onto the form and they both show up ok.

Did you chang its type or something? It seems there might be some bugs with changing the type which I will have to take care of.

You could try deleting the message field and adding it again.

What options are you using for the new fields?
