Title: Checking your browser… Last modified: August 30, 2016 --- # Checking your browser… * Resolved [joelo13p](https://wordpress.org/support/users/joelo13p/) * (@joelo13p) * [10 years, 8 months ago](https://wordpress.org/support/topic/checking-your-browser/) * Hi everyone, * I found out that when someone visits my site for the first time, a message saying Checking your browser.. appears and then the page redirects to the original url added ?ckattemp=1 at the end. * I don’t know why it appears or of it is a plugin. * The page saying Checking you browser seems to be using a script called aes.js and using cookies. * This is giving me problems with google indexing my site pages. It happens with every single page in my site (even the sitemaps). * Please help me out with this.

In the last 24 hours I have learned that aes. js is a Google Crypto JavaScript that enables safe running of the aforementioned. The problem isn’t the script it’s that way the script is being called. The html syntax is wrong. The opening tag is where the call is unfortunately I can’t locate it. It’s not in the “header.php” and I’m not sure where to look. This is the problem “Error Line 1, Column 1: no document type declaration; implying“ ”
