I guess I'm a little confused between the two methods of whitelisting, as mentioned above. Perhaps it's due to to my lack of knowledge about php.
I use the meta.php hack as I have for years prior. When that method is employed, I see the fields on each post in the wp-admin backend. However, when I revert my meta.php As Parneix notes in step 1 above, and insert the code per step 2, I get nothing on the backend of each post.
Should I just assume that it will save this information or should I be seeing it somewhere? Also, what does the patch for wpseo-non-ajax-functions.php have as an advantage over hacking the meta.php file?
