You have attempted to create your playsms VirtualHost under your Apache Root (/var/www) when the local user should be /home/playsms
The web site for playsms can go under /var/www but your local account should be /user/playsms
You can follow the 1.4.3 instructions under ubuntu 18.04
Change /home/komodo to say home/playsms (or leave it as komodo)
pay particular attention to
5.1. Prepare Directories
Here are some important directories that need to be ready before playSMS installation:
/home/komodo/public_html
/home/komodo/log
/home/komodo/bin
/home/komodo/etc
/home/komodo/lib
/home/komodo/src
In the end, for my installation, I copied this structure and did not attempt to put the logs in /var/log/ and configs /etc. Permissions are easier when it’s all in the local user’s home directory.
