ok i messed up: ProFTPD terminating (signal 11)

Hello guys,

im kind of new to virtualmin and everything and to this date i could solve everything by just using google or looking at this forum and some very helpful posts some of you made.

but i couldnt find anything that could possibly help my stupidity in this situation.

so here is the problem/story:

i'm usind pro and hosting some domains / subdomains on my vps and just the letsencrypt ssl cert for my own domain. then i noticed i cant use ftp anymore, i thought it might be cause i added the certificate to proftpd aswell. well, projects hosted on subdomains couldnt connect via ftp either. since theyre gonna get either outsourced or hosted on their respective buyers servers i didnt think this is a big problem, well its still a problem and i didnt want it to become any bigger than it already is.
so i disabled SSL for my virtual server because i didnt see any other option of removing the ssl cert from proftpd and reennabled it - genius, ikr :/.

so i tried to connect over and over again with different logins, tried to add new ftp users and so on. turned out proftpd wasnt running. i thought i could just reinstall it and recreate users. but first: i really dont know how - and second: i dont wanna mess up more than i already did.

so this is the error message i get when i try to launch proftp from webmin panel under "servers":

Starting proftpd (via systemctl): proftpd.serviceJob for proftpd.service failed. See 'systemctl status proftpd.service' and 'journalctl -xn' for details.
failed!

this is what i get once i type proftpd --configtest in putty

root@kebabmeal:~# proftpd --configtest

systemctl status proftpd.service gives me this:

also there is something with wrong with smtp i guess now that i'm looking at it -_-

this is all the information i could think of, if any of you need any more stuff i'd be more than happy to provide the missing info.
i hope this is fixable in some way.

edit: kebabmeal is just the placeholder for hostename /username
