diglog, can you please make sure these issues don't occur again?

Bug 1:When digging items, sometimes only the category "Technology" appears, while "Entertainment" and "Video" do not show up. Refreshing doesn't help.

Bug 2:Unable to log in, specifically unable to log in on the Diglog homepage. It remains in a logged-out state; after entering the username and password, it still shows as logged out. Actually, I am already logged in to my "Quasimo's Bookmark Blog", as I am writing this post right now. However, when I return to the homepage, it still prompts me with "Please log in."

I'm not sure if these two issues are unique to me or something else, especially the first one, which has happened more than once.

The second issue seemed to have occurred before, and now it’s unclear whether it's due to the redesign of the "upvote" feature.

Now there's more AJAX functionality, but it doesn't necessarily feel better than before.
