BF PORTAL -> Save was not successful :(

Anyone else having issues when trying to Save. i keep getting a message "Save was not successful" when trying to save or create New mods. I can create a new mod and save but once i try and save after i use "Rules Editor" it says "Save was not successful" ☹️ everything was fine until today a couple hours ago. Been trying since to edit or make a new mod with zero success.
