In my case, even just opening the library (
https://mangadex.org/titles/follows) was giving this error:
The webpage at https://mangadex.org/titles/follows might be temporarily down or it may have moved permanently to a new web address.
But, the canary.mangadex.dev domain still work so maybe the issues is: the dev disabling the main domain for awhile, maybe migrating something, or fixing something, or else.
Edit: now even in canary, mine got that bug too (the bug of title can't be showed/showed No Title error). Even my access to forum became unstable. Sometimes it accessible, sometimes I got the warn that the forum can't be accessed though my internet is okay and my network configuration not changed at anything.
Edit 2: I think I dropped a wrong message here since what you guys actually talking abt the
MOST POPULAR TITLES, not about the bug I mentioned. AAaa I'll die on embarassment!!

But I think I'll not delete it to make people learn that when you are a bit unfocus, the solution is drinking water and not messaging in forum
