How to fix 550 error when writing file to vds with proftpd and webmin?

Question

webmin

Installed proftpd with webmin on vds with Ubuntu 14.04
I created an account, I connect, I want to edit the file.
Issues:
Command: PASV
Response: 227 Entering Passive Mode (188,188,42,133,195,55).
Command: STOR access.log
Response: 550 access.log: Permission denied
Error: Critical error while transferring files
Concluded that there are problems with rights. Assigned rights to all folders for the ftp user i.e.
chown -R ftpuser:ftpuser *
Yes, in this case, all files are written via ftp, but Bitrix or WordPress refuse to work correctly, because. I can’t record files myself, it’s just not possible to upload a media file or install a plug-in.
How to solve this problem?

Answer 1

Most likely they are trying to create a temporary file, and are denied. Make ftpuser the owner of the directory one level up so that new files can be created in the current one.
