Why any lichess forum page 50, 51 etc gets me 404 error?

It is on any lichess subforum. And starting exactly at page 50, can't get past page 50 - getting error 404...
Is it a bug or what?

Hmm I ran into the same problem @Terinieks . They are probably too old and 1. Lichess would crash and 2. people probably aren't interested anymore. You can always bring back a topic by searching for it.

Page 49 is still only 1 week old topics. Can server really cant handle it?
Yes search can be used, but I dont know all the possible topic names with great info within them.

Can some more people confirm that they cant reach page 50 or more?

Yes,same thing here.
