Welcome to the forums @PascalURSO! Can you please provide a link to your repl?

It’s a blank new php server (not any file added or modified).
https://replit.com/@PascalURSO/chat-php?v=1

Is that repl private? Returns a 404 for me.

Should be publicly accessible (I have tried access on incognito browser)

Not for me, could just be a bug though.

Strange… anyway, you could try by yourself on a new php web server project

Strange, it’s a bug, for some reason the app won’t open the repl but I can still open it in my browser on my phone…

Strange, I will put that in it’s own bug report then.

it seems they forgot about UPM when making the nix templates. Files > ⋮ > Show hidden files. Add to the .replit file:

[packager]
language = "php"
[packager.features]
packageSearch = true

Then, add pkgs.php82Packages.composer to the replit.nix file. Now you should be able to search for and install packages.
