If I roll back to v3.x it works as expected.

This stack trace points to theUILang.speedGraphDurationOptions .
Let me guess. You forgot to copy the lang folder when upgrading versions.

[vendion]

No, I did copy the lang directory, in fact, I copied everything. The way I did the upgrade was I updated config/config.php to point to my rtorrent socket file and then ran cp -r ruTorrent-4.2.9/* ruTorrent/

[stickz]

Please try upgrading to v4.2.10. We resolved a web browser caching issue when changing versions, that could trigger this error.

[stickz]

No response from user. We presume this to be a caching issue with version upgrades which has been resolved.
