Hi, for me pure FTP has a lot of issues on Webuzo. The Webuzo team is informed about all this issues because I'm reporting since long time.
recently I get again in touch with Webuzo support because if you set TLS 2 in pureFTP config after some day, weeks, etc you can see TLS 1 added at the end of the file so allowing unsecure connection.
I get also error simply uploading an hesk 3.0 folder and removing it get many FTP disconnections.
Avout the issue you are reporting... yes, you can edit pure FTP and try to restart but settings seems to be ignored.
WHY?
Have you tried from Webuzo panel to stop the FTP service than to refresh the services page?
Usually FRP service never get stopped so restarting is not helping. Also stop the service never help somtimes.
For resolve I need do the following SSH command:
pkill pure-ftpd
Thiswill kill all pureFTP process. After that you can try to restart and see if your config file get effect.
service pure-ftpd start
Pure FTP seems to me to be very old, is not updated since 2019
If I made some seach on the web I can see also mozilla and other website is not providing cnfiguration for SSL they use to show ProFTPD
