Error by opening the webui for the first time

I’m getting an error once I try to open the webui.
I’ve already installed the missing dependencies and restart the browser. But It’s still showing the same error.
I’ve tried it on chrome and firefox.

Please help…

When asking for help and support, please provide as much information as possible. This should include:

  • Steps to reproduce an issue.
  • The output of ./validate.php

If it’s an issue with the WebUI then please consider including the browser version you are using.

If you need to post any text longer than a few lines, please use a pastebin service such as https://p.libren.ms using non-expiring pastes.

Did you run ./scripts/composer_wrapper.php install --no-dev ?
If the php list is in alphabetical, its missing mbstring extension

The VMs are a little bit outdated

Ofc i’ve run it as the screen-shot shows.
I also updated librenms right after installation by using:
cd /opt/librenms
./daily.sh

How to add that missing ini ?

sudo apt search mbstring and install the correct php 7 mbstring package with sudo apt install package

It has solved the problem. I’m in the web interface now… thank you !
