As I’ve answered on our own support forum, the errors are not caused by Mantra but by HTML errors in your page.

That’s normal behaviour. Mail links need to have mailto: in front to work.

Mantra somehow lost its settings (or part of them).

You’ll need reset WordPress to a different theme (by renaming the “mantra” folder to something else) so you can use access the Dasboard, then uninstall and reinstall Mantra to make it reset to the default settings.

Version 2.0.2 will hopefully prevent this issue from ever happening again.

You might be using version 2.0.
Version 2.0.1 fixes this.

Use this custom CSS:

.current-menu-ancestor, .current-menu-parent, .current_page_parent, .current_page_ancestor {
    background: white !important;
    box-shadow: none !important;
}

There are no built in options to change the top menu looks. You’ll need to do that by hand with CSS.

You should not add anything in the theme files. Any changes you make will be lost on every update.
Use Mantra’s dedicated custom CSS / JS fields in the settings or consider creating a child theme.

Use a custom menu – https://en.support.wordpress.com/menus/

You can also create custom menus in WordPress – https://en.support.wordpress.com/menus/

Mantra has an option just for hiding the site title and description…

Are you using any comment-related plugins?

I stepped on the same issue myself.

tondy, just edit that file dinamic-to-top/uninstall.php and add the missing “d” so the last line reads

delete_transient( 'dynamic_to_top_transient_css' );

Or just use Mantra’s own “Custom CSS” field to write in simple custom CSS without over-complicating things with child themes.

You are using the Mobile View option. It automatically resizes videos to the content size (to make them fit in mobile browsers windows).
Disable that and your videos will display with their set size.

On Riot Reactions we use Ubermenu (a commercial plugin) for the main menu.
You can customize the menu design in Mantra using CSS.
