Some versions of Google Chrome does not have “cross domain support”.
XKit needs that because it accesses my server at www.studioxenix.com to download and install required and optional extensions, as well as updating itself and showing the Extension Gallery.
If you are using the latest version of Chrome, and still experiencing problems, you might need to install one of the following scripts:
I am really sorry about this, but this problem rises from the fact that Chrome does not implement certain userscript/greasemonkey functionality properly.
Then, please reset XKit by following this link:

Please send me an ask if the problem continues even after installing these extensions and updating to the latest release of Chrome. Be sure to take a screenshot of the JavaScript Console. (or at least write down the error messages you can see.)
Thank you. =)
