Blog Posts and WooCommerce Products Not Updating

No blog posts or products on the site will update, new products or blog posts can’t be added. When clicking save/ update JavaScript attempts to do something as the loading circle actions but nothing else happens.

I have flushed cache, increased memory limits, variable limit, checked the page’s JavaScript – all of the common fixes for this sort of error.

Any ideas?
