HI Mekki, I was coming here to get some help and the fact that nobody has replied to you means that I’m probably SOL.
But… I have been setting up LIbreNMS with 22.04 and PHP 8.1 and ran into the same problem. I’m not sure if I had it on 7.4 or not, but regardless of that…
I believe this is a bug, but what happens is that some code looks at your weathermap directories and throws up on it because there isn’t a map file. Something gets a null and it crashes Libre immediatly. YOu can however go to the editor and create a map even when Libre is blowed up. (technical term).
Go to your server /plugins/Weathermap/editor.php… So http://librenms.whyme.com/plugins/Weathermap/editor.php and then create a map. You might need to go in there and change those output directories, but if you can get a map saved, it will fix your librenms and then you can go nuts. I hope this helps.
