Just FYI, I did the auto update Rel. 15 7/24 and received an error:
Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 82197 bytes) in /home/content/47/8086347/html/wp-content/plugins/speedy-smilies/functions.php on line 371
Had to delete SS folder through FTP to get my site to return.
My theme is Graphene.
I have not done a redownload and install yet, but I will try.
