Tvheadend

"comet failure [e=Cannot set property 'innerHTML' of undefined]"
It's incredible that through all my Googling for a fix to this issue, that no one recognises this to be a simple JavaScript error message incorporated into TVheadend. It is being returned when I try to map services. Apparently, TVheadend has a JavaScript bug that is calling a particular command to load data into an Object Model element that hasn't been loaded yet. This is definitely an issue that TVheadend's developers need to look into. I am seeing this complaint all across my Google searches without any answers and some of them are very old. This doesn't seem to be browser specific because I receive this error with Chrome and Firefox.
