Problem after update to MyBB 1.8.6 (from 1.8.5)

[utku618]

my problem is about the slowness of the admin panel. when ı updated the 18.6, my admin panel was very very got slow, and then ı saw the problem cause of google seo. I changed some codes in google seo.php. Google seo is not seem on my admin panel but forum is working comletely well.
it is not about the other problems.
