I just got back into playing this game and I've noticed that the daily quest boards do not give me quests...im not sure why but they're always blank for me. I went to my sisters room and when she goes to the towns the quests show up for her just fine.

the esior's haven quest board is a weird one- i'm not sure if it ever refills after you finish like, the tutorial quests or whatever? It's been empty for me for years, so that's been my assumption.
Sanctuary questboard should refill once a day so long as you've turned stuff in? I think? Honestly I last did a quest like, years ago, so I'm a bit hazy on the details.

If you can confirm that yours isn't resetting with new quests even when all the ones you had have been completed, especially if it is doing it for your sister, you could try bug reporting?

The second area is now that ive completed the tree, i had already messaged an admin and i feel bad about it now, but i did mention that quests dont appear there and asked if it was intentional or not, we shall see
