Problem with w3 validation

Hi there,

Are you talking about this one?:

Bad value for attribute href on element link: Illegal character in query: | is not allowed.

If so, you can fix it with this filter:

add_filter( 'generate_typography_google_fonts', function( $google_fonts ) {
    return str_replace( '|', '%7C', $google_fonts );
} );

Let me know :)

No Tom. I have seen your answer about this issue in another post. I am talking about script with a src attribute and type with different value from the proper one.
Do you have any idea why this happened?

Ah, WordPress adds those by default. There are ways to remove them, but it's really not worth doing in my opinion.

If you want to go ahead and do it, this should help: https://wordpress.stackexchange.com/a/287833/90661

Thanks Tom for your answer.

I have to do that because my client needs a zero error report.

Finally, I resolved this. This strange string before type is added from RocketLoader of Cloudflare! When I disabled it, the strange string disappears.

Thanks a lot for your help. I hope this post could help someone else in the future!

Glad you got it fixed - thanks for sharing what it was :)
