In a system I work with, I'm logging all information about the running of the said system.
As such, we get a lot of diagnostic information which are otherwise ignored by regular installs. This allows us to issue "advisories" to plugin authors (and WordPress itself) to help them fix potential issues in code.
As such, I would like to report my findings on AIOSEOP plugin:
[aioseop.class.php : 1155] Notice: Undefined index: nonce-aioseop-edit
[aioseop.class.php : 1154] Notice: Undefined index: aiosp_edit
Kind regards, Chris.
