For now the extension is working.
I just discovered is not update since long time so I implemented the pull request that are pending on GitHub, seems no issues. I don't know if that 8 pull request is enough to just be secure but I done.
The extension is working but as it is currently can miss security update that are in the pull requested made by a GitHub bot.
I simply replaced the JS file with the one committed by the GitHub bot and seems all is working abut gain I don't know if is enough 🙂
Will be nice in the future think Flarum can still support the infinite scrolling 🙂
