Minify is breaking YOAST JSON-LD Meta
-
I’m running W3 Total cache alongside a couple of other plugins, one of which is yoast.
Yoast outputs the following:
<script type=”application/ld+json” class=”yoast-schema-graph yoast-schema-graph–main”>……
This contains a ‘CDATA’ element to associate our sites with our social accounts etc etc.
Now with ‘Minify HTML – inline CSS & inline JS’ switched OFF – this works fine, however once I switch ON ‘Minify HTML – inline CSS & inline JS’ i’m receiving the following error in my Console.
[Facebook Pixel] – Unable to parse JSON-LD tag. Malformed JSON found: ‘/*<
-
I’ve made the following changes to the Yoast file “inc->class-wpseo-utils.php”
/** * Returns a script tag with Schema blob. * * @param array $graph The Schema graph array to output. * @param string $class The (optional) class to add to the script tag. * * @return false|string A schema blob with script tags. */ public static function schema_tag( $graph, $class = 'yoast-schema-graph' ) { if ( ! is_array( $graph ) || empty( $graph ) ) { return false; } $output = array( '@context' => 'https://schema.org', '@graph' => $graph, ); //HOTFIX Find "& #39;" and replace with a ' //HOTFIX Find "»" and replace with a - //return "<script type='application/ld+json' class='" . esc_attr( $class ) . "'>" . self::format_json_encode( $output ) . '</script>' . "\n"; $return_string_json = "<script type='application/ld+json' class='" . esc_attr( $class ) . "'>" . self::format_json_encode( $output ) . '</script>' . "\n"; $return_string_json = str_replace("'", "'", $return_string_json); $return_string_json = str_replace("»", "-", $return_string_json); return $return_string_json; }This seems to have fixed the issue but obviously not an ideal fix as it will need to be copied over every time yoast updates and does not account for any other HTML entities that appear on other pages. If you can recommend a better fix for this issue it would be much appreciated.
Many thanks.
