This morning i tried to change the video size of one of my youtube videos. I used the shortcode, but i’ve made a mistake, i copied and paste the embed code with different size instead of the youtube adress.
Of course it didn’t work, so i erased the line.
Since i did that, EVERY videos on my blog are showing with black bands all around.
No problem once we push “play” but the preview images are now ugly.
Each time i use the shortcode “insert video”, i have this problem, whatever the format i try to use.
I’m not seeing any black bands on my end. Did you get this fixed?
