Hello @gkobler it’s interesting that this was working in version 11.2.3 but not 11.5.7. It looks like the requirements are stricter.

We dont develop emoncms with shared hosting in mind and the errors look related to this. It is trying to access both the function passthru (which should exist PHP: passthru - Manual) and the serial port locations which must be restricted on your system.

Could you move your system to a VM based service such as DigitalOcean droplet? (cheaper options exist I believe… DigitalOcean Droplets | Scalable Cloud Compute Starting at $4/mo).

Hello @TrystanLea

I have since found out that the PHP setting was lost due to the PHP version change. The passthru must be explicitly activated with my shared webhoster.

I have contacted the support of my webhoster to have it reactivated.

Self-managed VMs are not a good option for me because I don’t want to worry about the security of the system. That’s why it has to run on a shared webhoster.

I am also aware that this can lead to problems.
