Hi @phpteam
When I checked the pages source, I noticed your site is running Yoast SEO 22.7. Kindly update Yoast SEO to 23.8. Then check the metabox.
Update Yoast SEO:
Before we discuss manually updating, let’s cover a few important things to be aware of beforehand. First, Yoast SEO stores SEO data and settings in the database, so manually updating is not expected to cause any data loss.
Second, we recommend creating regular backups of your site and database for your site’s health and safety. This is especially important before installing, updating, or removing plugins. It provides you with a safety net in case something were to go wrong. Learn more about the benefits of regular backups.
Kindly follow the help article to update the free version of Yoast SEO.
Disable sitemap:
Once Yoast SEO is updated to 23.8, kindly head to WordPress dashboard > Yoast SEO > Settings > Content type and find slide-page or avada-faq and then disable those from Search appearance. Save the settings.
