Me and other people are having the same problem: blanks in admin panel OF PLUGIN (not in admin panel of wordpress). I had some replies to my problem, but all the time the same: ''removed the "s" from update_options() on line 441 of wordpress-seo/admin/class-admin.php''.
NO, this is not the problem because my line 441 is: uptade_option() (the last version of plugin 22.214.171.124 has solved this problem in line 441, if you download it you will see it in its changes).
I got the plugin from some days ago and I'm having problems. Bad experience. I understand that sometimes it can have errors, but I commented in this forum that the problem is not with 441 line.
Will I have to replace the last version 126.96.36.199 for 1.2.7 version, because I have not answers about this problem???
I use wordpress 3.4.1.
