How to fix Piwik not working when https protocol is enabled

If you noticed that your Piwik has stopped working when enabling SSL or it never worked in the first place using https, you may be having issues with the protocol. Most hosts only allow SSL for one subdomain (usually www) unless you order an expensive package so if you happened to install Piwik on a subdomain (say while SSL will work, an exception will need to be made as the certificate doesn't match the exact URL.  Because of this, piwik will not load the scripts correctly.  Luckily this is simple fix.

  1. Make sure SSL is the problem
  2. Update the tracking script

Step 1:

To make sure that SSL is a problem you have to try to load the piwik.js file from your installation folder using both https and http.  By default, mine was trying to use https and it was showing something similar below in firebug. If it shows the piwik.js source code then this is not your issue.

Alternatively you can open the file in the browser by going to:

If you get a confirm secuirty exception (in firefox) or if you get a message similar to the picture above, then this is indeed an SSL problem.

Step 2:

To fix this, all that is needed is to change the tracking code snippet to always use http instead of http.  Your tracking code should look similar to below:

<!-- Piwik -->
<script type="text/javascript">
var pkBaseURL = (("https:" == document.location.protocol) ? "https://" : "");
document.write(unescape("%3Cscript src='" + pkBaseURL + "piwik.js' type='text/javascript'%3E%3C/script%3E"));
</script><script type="text/javascript">
try {
var piwikTracker = Piwik.getTracker(pkBaseURL + "piwik.php", 1);
} catch( err ) {}
</script><noscript><p><img src="" style="border:0" alt="" /></p></noscript>
<!-- End Piwik Tracking Code -->

All that is needed is to change the pkBaseURL to always be so change the pkBaseURL line to:

var pkBaseURL = ("");

And that's it, save your changes and retry!


  1. Hi this post helped me to fix my problem, although the actual probelm is that my page was technically on a subdomain eg even though really it should be just

    This was having some weird effects and leading me to a different page not owned by me

    I confirmed this by seeing a security message from chrome when trying to access the page that piwik was using.

    All I had to do was go into my hosting cpanel and redirect to

    Then I was able to go to the wordpress plugin wp-piwik and use the rest url as (before I had to use because of problems with it in hostgator)

    Sorry if that makes no sense, hope it helps someone

  2. I doubt that this will _really_ solve your problems. Or to rephrase: you will probaly get new problems. At least IE will moan at your users that there are unsecure scripts in your page.

Kivy vs React-Native for building cross platform mobile apps

I've built three apps now using Kivy and one with React-Native, just wanted to share my thoughts on both. Just a warning, I am strongly biased towards python and this is all based on opinion and experience and is thus worth what you pay for it. I don't claim to be an expert in either of these, just have worked with each for several months.  If something is incorrect I'd love to hear advice. Kivy Demo of one of the apps Pros: Nice to be able to run natively on the desktop WITHOUT a simulator Python is easy to work with Use (almost) any python library Very easy to create custom widgets Kivy properties and data binding just work. Way nicer than React's "state" / flux / redux whatever you want to call it (stupid?).  Native interfaces (pyjnius) and (pyobjc) Runs and feels pretty smooth Cons: Default widget toolkit looks like Android 4.4. Requiring you use your own widgets or a theming kit like KivyMD  if styling bothers you Creating dy

Control Systems in Python - Part 1 - Bode and Step Response

I hate matlab with passion, yet sadly, nearly everyone uses it.  I'm a fan of Python and open source stuff so here's a simple article on how to do some common control systems stuff in Python. First we need to make sure the environment is setup. Install IPython (or you can use any other python shell, but a unicode supported shell is preferred) Install python-control (numpy, scipy) Install sympy These should do if your on Ubuntu/debian: sudo apt - get install python - sympy python-numpy python-scipy python-matplotlib ipython Then you need to install python control, see How to download and install python-control Intro to using Sympy Open ipython and run the following: import sympy from sympy import * sympy.init_printing() s = Symbol('s') Now we can do things like define transfer functions using the symbolic variable s. We can expand the bottom using the .simplify() method and we can do something more complex like... which is really nice because it

Control Systems in Python - Part 2 - Routh Hurwitz

In my last post Control Systems in Python Part 1 , i described how to setup and use Python for doing some basic plotting of transfer functions. One of the biggest benefits of using sympy vs numeric packages like matlab/numpy/scipy is the fact that you can use symbolic variables. This post includes a function for computing the Routh Hurwitz table (Note: It does not work for row's of zeros). Lets do my control systems design homework problem together :) (Warning: I have not verified if this answer is right so please correct me if it’s not!) The Problem The problem is DP 9.11 from Dorf & Bishop’s Modern Control Systems. ISBN 0136024580. Basically we have to design a controller to compensate for a system with a time delay. The controller is: And the system is: First we approximate the exponential term with a 2nd order polynomial using pade(0.4,2) such that: Thus the approximated system is: Using frequency response methods, design the controller so that th
