title: Wordpress don't recognize url parameters
body: <p>I'm using wordpress and developed an angular code to open a button in my DOM The calculated fields are correctly working, but I need to use a angular created code to display a button in according to an parameter (called campanha) value.
  Let me try explain th history:
  I'm working with Marketing in Google Adwords campaigns, and we created 3  campaigns, (one for Brazil, other for US and other for UK, i.e.), and the values of each campaign are sent to me through the Google search page.</p>
  
  <p>Below I have an example from what I'm talking:</p>
  
  <pre><code>&lt;http://www.redecidada.org.br/calculo-cota-aprendizes&gt; (working)
  &lt;http://www.redecidada.org.br/calculo-cota-aprendizes?campanha=mg&gt; (404)
  &lt;http://www.redecidada.org.br/calculo-cota-aprendizes/?campanha=mg&gt; (404)
