Having the same issue, everything else is working but when I click on the timeline it won't load and I only see the default World Anvil background. If I reload enough times I get an "Error 404" page.

Moving these notes from another ticket because I've had the same issue along with related issues since yesterday and before:

• Text that's been entered disappearing. (examples: a [ /p ] tag where the /p disappeared in the middle; text disappearing from articles, text in timeline events reverting to versions from two or three updates prior)
• My timeline just vanished while I was working on it. I made edits. It said it saved. Then I checked, and it reverted, so I refreshed, then I just had the wallpaper, and I haven't been able to reopen it in Opera or Chrome.
• I can view my timeline in my world but when I click the edit button, the edit options don't come back up.

I've found a work-around that works on Opera, where if I view my timeline in my world, I can click the edit button and select a world event and edit it. But it doesn't open the usual tab bar at the top of the screen still, and it reverts back to what it was before the edit until I refresh the page. Hope this helps.

I had this issue as well along with stuff simply not saving after it's been written
