THEMA: My videos always give error

Hello Dear Admin,
My videos always give error, please help me?

What kind of errors? Can you send details? URL? Type of video? Screendhot?

They all, I click to see and in the end there was an error and did not count the credits ... but now it seems to better. Thank you

Everytime I try to add a video I get this error:
We can't find this channel: https://www.youtube.com/channel/. Please make sure to enter only the parameter behind /channel/
Example: https://www.youtube.com/channel/mychannel
Click on the channel name under the video to find a channel url.

I dont want to add a YT channel..I want to add a video wtf.....

This problem should be solved.
