Looks like pagination is broken in 1.5.0? A few of my users reported issues, but I can't even enable pagination on my forums.
See these issues on Github:
Admin panel seems completely broken
Testing ground is broken on mobile
Partial not loaded: partials/noscript/paginator.tpl
[v0.7.0-dev] I might have broken the Extend > Rewards page by accident...?
Internet connection broken while running upgrade
nodebb-plugin-session-sharing broken in 1.7.2
App broken (unrecoverable theme)
