Thanks for sharing this with us. We are currently busy with the next release (1.29) but I will have a look on the configuration tomorrow. Hope this helps.

@tippexs, Did you get chance to look into issue?

[tippexs]

Working on it today. Will let you know later today. Sorry for the delay.

I was able to reproduce and fix the issue (Unit 1.28) by applying chmod -R 777 to /home/demo1/ which includes public_html. Applying the Unit configuration and afterwards switching back to 775.

Also, I was able to use the isolation using /tmp/ as the rootfs? Can you try this in your system?

We will have a look into this and I need to test this with 1.29 as well. Sorry for keeping you waiting soo long.

@tippexs it works when I changed chmod to 777 for /home/demo1. But I want it to keep 711

[tippexs]

I know. 0777 is not the solution and we will investigate this. Thanks for testing.
