Hello Arthur,
We were able to reproduce the issue on your site but after a while it seems like after I logged in again it redirect me to the correct page which is community page.
We suspect it might be the hidden menu item that you've created that is pointing out to the easysocial dashboard at your homepage. I see that you've change it to view single article just now while we debugging.

By the way may I know if the issue is solved now?
Please advise.
