Recordings not working after installing LiveTVH 1.4

[segadude]

After updating to LiveTVH 1.4, I am no longer able to access my recordings through the LiveTVH plugin. When I select the recordings item within the LiveTVH plugin in Plex, it says "This plugin is not responding." I took a look in the log for the LiveTVH plugin and saw this:

2018-10-10 14:12:39,314 (7f0f95ffb700) :  CRITICAL (runtime:889) - Exception (most recent call last):
  File "/usr/lib/plexmediaserver/Resources/Plug-ins-10d48da0d/Framework.bundle/Contents/Resources/Versions/2/Python/Framework/components/runtime.py", line 843, in handle_request

I am running Plex Version 3.67.1 and Tvheadend 4.2.6-79~g0678cb1ad on Debian 9.5. I was able to access the recordings fine on an older version of LiveTVH before I updated to LiveTVH 1.4.
