I have about 16 pages in my wordpress backend. As soon as I activate the Yoast SEO plugin, about half of those pages disappear from my WP Admin area. Luckily, they are still visible for site visitors, though...
I am using the "Enfold" theme from Themeforest. PHP memory limit has been increased – which didn't solve the problem. The template programmers said they're not aware of any such problem.
Could someone please help?
Thanks a lot!
