Is your WordPress site embedding tracking code without your knowledge?

I just stumbled upon a couple of important articles relating to the WordPress Stats plugin available for free to all wordpress users and gives a sort of cut down Google Analytics functionality. i found the articles because i was googling as to why all of a sudden my sites were loading a file from, I wont rehash the details and instead link you to the 2 respective blog posts and summarise with these points, full info is available at or at

  • The WordPress Stats plugin now includes a call to the quantserve sites for “planned extra features”
  • They have not acknowledged the inclusion of a 3rd party data tracking script in there plugin on the plugin main page
  • they have not offered ANY opt in or opt out procedure and look to be unwilling to do so
  • The js file in question can and seems to lower website performance by a noticeable margin

However there is a solution for users of the of the WordPress Stats plugin: install this plugin made by futta which will disable all tracking possibility with quantserve (do not install if you actually use quantserve) and let the developers of the WordPress Stats plugin know that you are unhappy with the inclusion of 3rd party data tracking without your knowledge and without an opt-out facility.

I’m also going to consider asking futta to submit the plugin to the wordpress plugins database.

This problem highlights the need to be vigilant and careful about what plugins you install on your wordpress site

HOWTO: Upgrade Debian Lenny (5.0) to Debian Squeeze (6.0) on

Here are the working upgrade instructions from Lenny to Squeeze (Debian 6) on

Disclaimer: please test this yourself first on a NON PRODUCTION SERVER. this may or may not work with other server providers but is specifically tailored to the system, I do not guarantee its results outside of my tested system (OnApp Cloud – LON-I from a stock Debian Lenny install).

UPDATE: have now released Debian 6 templates on there clouds however upon testing this i have noted several issues with it and as such although it makes the install of debian 6 easier on i am not however recommending using the Debian 6 templates that until they fix the bugs with them – the biggest problem so far is that you cant update the kernel without a fatal error which will occure everytime you use apt to run any updates (which you should be doing regularly), there are also issues with sub-optimal mirrors being selected and at least from what i can see wrong timezone by default in LON clouds. At this time because of the kernel update issue you cannot install ksplice and possibly any program that uses a shell script that interacts with apt for installing.

Other notes: Ksplice is known to work with Debian Squeeze, also despite having success on the older clouds (eg LON-C) I havent been able to document possible pitfalls with non OnApp based clouds therefore its recommended to first TEST your upgrade in any instance and/or migrate to the newer clouds if you can. I assume you can SSH in as root to your server and can handle basic file editing with nano (substitute your preferred text editor as neccesary)

Here goes:

Fully update your lenny system (recommended to avoid some possible gpg errors).

apt-get update && apt-get upgrade

I recommend rebooting here just as a safety measure.


Reconnect to your server then update your apt sources list.

nano /etc/apt/sources.list

Your sources list should look not to different to the following (for UK servers) update the references appropriately to get the closest mirrors to you:

deb squeeze main
deb-src squeeze main

deb squeeze/updates main
deb-src squeeze/updates main

deb squeeze-updates main
deb-src squeeze-updates main

Update the package lists.

apt-get update

Install locales update (to stop lots of annoying errors while upgrading).

apt-get install locales

Update the kernel and install udev first.

apt-get install linux-image-`uname -r|sed 's,[^-]*-[^-]*-,,'` udev


When asked for change to UUID’s – select NO

Now edit your /boot/grub/menu.lst and edit any reference of sda1 to xvda1 (should be 3 of them).

also edit your /etc/fstab file and change an references from sdaX to xvdaX  (should only be 2 items)

Then reboot again.


Reconnect to your server and check your kernel version.

uname -r

Should return something starting with 2.6.32 similar to:


Then the final upgrade.

apt-get dist-upgrade

When you are asked for options.

Change to dash – doesnt matter which is chosen this can be whatever you prefer.

Chainload grub 2 – NO.

Change to dependancy based sequencing (i selected both and its fine).

Restart services just hit enter.

Reboot for good luck (isnt actually needed because kernel is already up to date but better to eliminate issues ahead of crunch time).


Sit back and Enjoy!
