I posted this exact question over on the plugins homepage but I got no answer, so here is my question again:
I just noticed a huge problem I have with your plugin. I hope my diagnose is not wrong.
I just noticed, that all my posts had their meta keywords twice in the header. I checked for other plugins I might be using, found none, deactivated your plugin and they were all gone. I reactivated, and they were back.
Then I edited this post: http://pacura.ru/pictures/fatboyslim-mamaia-beach/the-company and deleted the keywords I had manually specified in the AIO fields. Saved, refreshed and now the post, has its keywords only once.
It seems your plugin takes the keywords from the tags, then adds those I manually specified and the result is all my keywords appear twice.
I am pretty sure I have not had this issue before, I have been a very long-term user of your plugin, going back to the times you had severall daily updates. Do you have a suggestion how I can easily repair this without editing all posts manually?
What about a setting to take the tags and convert them into keywords only if the post has no manually specified keywords?
