Belly, are you using version from Github, and not from the first post of this thread?
The version at our Github site should have fixed that control panel error 2 years ago. 1.43 is the version I think.
Also, you mentioned over several various posts you've tried editing on your own to prevent client side from showing.
If you DO NOT edit the code, and use the Github UTime version, do you still get errors?
Try this BEFORE deleting anything.
