Hi,

After customizing DBman to install it on my site, I tried to add a record, but it came back with this error:
Error: Can't add record
. o can not be left blank

Certainly, I haven't got 'o' field.
Checked it in the default, changed every field's settings to 0 for not required, but I'm still getting this error.
Please, could anyone help me? I have no idea what I did wrong.
Thank you in advance
