Running on Ubuntu 16.04.3 LTS 64-bit. I have set the API key via the :WakaTimeApiKey command, and the .wakatime.cfg file is present in the home directory. Other plugins requiring Python runs correctly (e.g. youcompleteme). The plugin was installed with vim-plug.

If you run this inside Vim, does it print 1 or 0?

:echo has('patch-7.4-2344')

[alanhamlett]

Can you try updating vim-wakatime to the latest version to see if it's fixed?

[hizkifw]

@alanhamlett Running :echo has('patch-7.4-2344') returns a 0. I've updated the plugin, it works perfectly now.
