WordPress just released a security update and version 184.108.40.206 as well.
Read all about it here.
Posting the security update below in case you don’t want to download and install 220.127.116.11:
- Open the wp-includes/template-functions-category.php file in a text editor like Wordpad.
- Go to around line 103 where it says get_the_category_by_ID.
- Create a new line after that and paste in $cat_ID = (int) $cat_ID;
Have upgraded mine and Melody’s blog to 18.104.22.168
