Hello,
We checked all the errors, here are some explanations
1. The “Elementor” plugin adds its own style tags to HTML, our theme doesn’t affect this.

In order to fix that error, you need to edit this image and add alternative text, go to Appearance -> Widgets -> select the “Footer Column 1” widget -> select the “Text” element -> in the “img” tag add the“alt” attribute.

Here is an example of the “alt” attribute for the “img” tag:
<img src="#" alt="footer-logo" style="#" />
