Adding new channel fields always says "The page you requested was not found." but editing fields works fine. Everything is working until we installed Profile:Edit module and even uninstalling it did not do the trick. Any ideas guys? Thanks in advance.
group_id
parameter which tells ExpressionEngine which Field Group you are trying to create a new channel in. If you are using the native Admin > Channel Administration > Channel Fields tools, please list any extensions you have installed.
