I have this problem too. Also after manually injecting a group, it isn't seen in webif and can't create any user. Ubuntu 20.04 x64

I just switched from mysql to mariadb in my Ubuntu 20.04 server setup and all is working fine now. I had the syntax issue even with proftpd alone, now it's all back to normal.
