log error

Hi,
Im trying to find whats wrong with kodi. In a lot of add ons (even subtittles and maintenance tool) i get the check log for more info warning.
Now i found how to check the log, but how am i gonna fix the problem.
The url i’m giving by logfile uploeader does not work, QR code does, but cant paste whole think in this post i assume.

Isn’t it easier and quicker to geinstall Kodi on my mediaplayer? Or does that not fix the problem?
How do i do that. Im kinda new to this.

Does anyone have some usefull tips or tricks?

Thanks u guys
