The height of video box have been increased on my website without reason. in all videos.
I had typical height-width of youtube box, but suddely changed height. Why???

Even I did not touch any configuration.
Any solution please?

 

I found this trhead with the same issue, is solved by disabling Lazy load or WP rocket , but I have NOT them installed.

By the way, I forgot to comment in my first post, that video modules are in columns.

is maybe caused by another plugin?

 

Sorry for security reasons URL can not be shared.
The issue is simple. Overheight in videos on columns.
Need only one solution to fix it please

You won't believe, another fatal issue related to the videos:

Now, are not displayed and getting this error;

The webpage at data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==?autoplay=1 might be temporarily down or it may have moved permanently to a new web address.

I found this thread with the same error, but nothing works, I have not lazy load installed.
