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:
Unsolved Missing icons / broken CSS
Internet connection broken while running upgrade
Admin panel seems completely broken
Partial not loaded: partials/noscript/paginator.tpl
Recent and popular RSS feeds broken?
Forum Traffic chart broken?
nodebb-plugin-s3-uploads is not using the S3 base url and all uploaded images are broken. Fix?
Avatars all broken since 0.9.0 upgrade?
