Got an issue with the Woo Commerce pages on this site. When you click the ‘Shop’ tab, a large image appears above the masthead. Originally it appeared an stayed. I spoke with WPEngine and they told me that the image is loading before the CSS. They purged the cache at their end and that seemed to prevent the image from staying there, but you still see a brief glimpse of it, even now, before the page loads properly.
Thanks for writing in! Upon testing your site, it seems to be related to WP Social SEO Booster plugin that you’re using. Could you please try disabling it first. If not, please disable all the 3rd party plugins and check.
Make sure to purge all cache before testing your changes.
