Hi chrisaliceko,
Maybe the problem is that your WordPress version is lower than 3.3, and is_main_query() function exists since this version.
If you don’t want to upgrade it, you can change the class-frontend.php according to: https://gist.github.com/Viper007Bond/1297669
It works me well.
Thank you webmag! I heard that Yoast’s plugin is the best, but some others says that the All-in-One SEO is the best. I used it a few times but I was not satisfied. That’s why I tried Yoast’s and I like it!
My main keyphrase is “Insiders Hub review”, but my domain is ends with “reviewed”, this is the reason why I use this in the title. Maybe it’s a stupid question, but will the site get penalty from Google if I change it to other than the domain exactly?
There is quite high competition in the TOP5…
