This is a new one for us. Bulk Handler seems to be excluding the FMFM tab fields. They are not on the .csv, just missing. Only this one server, others (same version/distro) have no issue. I can import the FMFM fields through bulk handler, I just cannot export them.
I will try, but i immediately thought I shouldn’t since I couldn’t replicate it on other boxes on the same FreePBX version. Sangoma will usually just close it in those cases.
