Thank you for fast response and fix, it validates perfectly now!

I can see w3 validator errors with this scheme urls, e.g. https://validator.w3.org/nu/?doc=https%3A%2F%2Fdev.nixys.ru

This site uses latest versions of Contact Form/Contact Form Image Capture plugins.

It show error:
Error: Bad value https://www.w3.org/2000/svg for the attribute xmlns (only https://www.w3.org/2000/svg permitted here).

e=”bot” /><svg width=”50″ height=”50″ aria-hidden=”true” role=”img” xmlns=”https://www.w3.org/2000/svg&#8221; viewBox=”0 0 576 512″><path

and warning:
Warning: Attribute xmlns is not serializable as XML 1.0. for the same tag.

If I replaced https to http manually, errors and warnings disappeared.

To be more precise: All pictures, used in captcha have incorrect xmlns attribute.

Here is error from validator: Bad value https://www.w3.org/2000/svg for the attribute xmlns (only https://www.w3.org/2000/svg permitted here).

xmlns – is not actual url to be used somewhere, but actually name for scheme, so it should be used as is.

You could check it in SVG specification: https://www.w3.org/TR/SVG/intro.html
