Hi I am running a local server running Ubunto 16.04LTS with a stock LAMP install that runs  stock Apache.

I have an install of WordPress under /var/www/vhost/{vhost-name}/public_html

Here is my problem.

I can either FTP or WordPress can edit / remove file.  I cannot do both.  Not sure why.

To allow WordPress to modify files I must:  (I cannot SFTP)

• chown -R {my-user-name}:www-data www/
• chmod -R 755 www/

To allow me to SFTP I must change the file ownership:  (WordPress cannot modify files)

• chown -R {my-user-name}:www-data www/

I would like to be able to FTP and allow WordPress to modify files.

Any help much appreciated.

Thanks!!
