Description of problem (please provide a set of steps we can use to replicate the issue, and make as many as you need.):
Step 1: Click on my iNaturalist bookmark (https://www.inaturalist.org/home). As per subject (https://forum.inaturalist.org/t/im-being-automatically-logged-out-of-inaturalist/20332), I then now need to log in since I am never remembered anymore, although the “remember me” button is ticked.
Step 2: I fill my details in and proceed to the site.
Step 3: I am automatically redirected to an “undefined user” page instead of my personal profile. This is new as of no more than a week. As it may be seen on the screenshot, my profile is well logged in, as one can see when hovering my avatar in the upper right corner.
Step 4: Clicking on my avatar finally leads me to my profile.
