do you see any error in console?

I'm used the filter to look for "spellpoints"

Found this one

that's not it, as you can see the message comes from "foundry.js"

errors usually have a RED background color like this:

The only two errors I get is these two:

[misthero]

wait, are you on dnd version 3.3.1?

[misthero]

spellpoints v2.4+ can only be enabled on dnd v4+

[Agentblank66]

Yes, I just updated the modules that was compatible with my version

This module didn't give me a warning of incompatibility.

[misthero]

Foundry compatibility only check the foundry version when updating, not system version.

you need v2.2.33 : https://github.com/misthero/dnd5e-spellpoints/releases/tag/v2.2.33

install manually using the following manifest url: https://github.com/misthero/dnd5e-spellpoints/releases/download/v2.2.33/module.json

than right click on the module and finally lock it so it doesn't get automatically updated until you decide to update dnd system too
