21, #24, and #28 provide support for Tmux 2.4. However, these are not yet in a new release. This is problematic when it comes to TMUX Plugin Manager, as it uses the latest release when determining what to install or upgrade to; since the latest release is 2.0.0, cut 3 years ago, the way keys are bound to copy-mode is incorrect, making tmux-open unusable.
You can get around it by manually doing the following:
$ cd .tmux/plugins/tmux-open
$ git checkout master
and re-loading your tmux configuration. However, a better solution long term would be a new release of tmux-open.
