Hi there,
I updated MetaBox to 4.15.8 and since then Yoast SEO is behaving strange. The input fields for Yoast SEO title and meta description disappeared. When I deactivate Metabox they're showing up, when activated they disappear again.
In console it gives these errors:
[object Error]: {description: "Unable to get property 'isSavingPost' of undefined or null reference", message: "Unable to get property 'isSavingPost' of undefined or null reference", number: -2146823281, stack: "TypeError: Unable to get property 'isSavingPost' of undefined or null reference at Anonymous function (https://xxx.xx/wp-content/plugins/meta-box/js/wysiwyg.js:102:4) at Anonymous function (https://xxx.xx/wp-content/plugins/wordpress-seo/js/dist/wp-data-921.min.js:1:8741) at Array.prototype.forEach (native code) at e (https://xxx.xx/wp-content/plugins/wordpress-seo/js/dist/wp-data-921.min.js:1:8719) at Anonymous function (https://xxx.xx/wp-content/plugins/wordpress-seo/js/dist/wp-data-921.min.js:1:25215) at a (https://xxx.xx/wp-content/plugins/wordpress-seo/js/dist/wp-data-921.min.js:1:12577) at Anonymous function (https://xxx.xx/wp-content/plugins/wordpress-seo/js/dist/wp-data-921.min.js:1:29405) at Anonymous function (https://xxx.xx/wp-content/plugins/wordpress-seo/js/dist/wp-data-921.min.js:1:29785) at onChangeAnalysisData (https://xxx.xx/wp-content/plugins/wordpress-seo/js/dist/wp-seo-post-scraper-921.min.js:1:101627) at value (https://xxx.xx/wp-content/plugins/wordpress-seo/js/dist/components-921.min.js:26:16979)"}

SCRIPT5007: Unable to get property 'clientHeight' of undefined or null reference
components-921.min.js (14,168097)
Don't know if this is a Metabox specific bug or it's on Yoast side but Yoast SEO seems to work correctly when Metabox is disabled.
Wondering if you know what's happening and if others have this error. I'm running WP 4.9.8, waiting to update for 5.0 like you recommended earlier.
