[Plugin: WP-Blocks] Apostrophe slash

Hey, if you’re still wondering (and this issue was driving me nuts), here is the solution.

go in and edit the plugin -> search for a function named

function get_wrapped_block_content( $data ) {
    $block = wp_kses_stripslashes($data['html_prepend']).wp_kses_stripslashes($data['content']).wp_kses_stripslashes($data['html_append']);

		return do_shortcode($block);
}

and add this line before the return statement:

$block = stripslashes($data['html_prepend']).stripslashes($data['content']).stripslashes($data['html_append']);
