title: Wiris math editor
body: <p>I need help. I installed the Wiris math editor, but it does not work. Creating math works well, but the display does not work. </p>
  
  <p>I know why, but I do not know how I repair it: I use free hosting which paste advertisement into the website's URL.</p>
  
  <p>I want the URL to look like:</p>
  
  <pre><code>http://u12.hys.cz/tinymce/js/tinymce/plugins/tiny_mce_wiris/integration/showim‌​age.php?formula=3b1e36f0f64404ca46029248411a14da&amp;cw=20&amp;ch=13&amp;cb=12&amp;text=55 
  </code></pre>
  
  <p>while my provider changes it to:</p>
  
  <pre><code>http://u12.hys.cz/%3Cdiv%20style=%22%20background-color:#; font-size: px;"&gt;&lt;div class="trop"&gt;&lt;strong&gt;Magnetická &lt;/strong&gt;kostka &lt;a href="http://unimagnet.cz/20-k-d5-neocube-216kusu.html" title="NeoCube"&gt;NeoCube&lt;/a&gt; na prodej&lt;/div&gt;&lt;/div&gt;/tinymce/js/tinymce/plugins/tiny_mce_wiris/integration/showimage.php?formula=3b1e36f0f64404ca46029248411a14da&amp;cw=20&amp;ch=13&amp;cb=12&amp;text=55
  </code></pre>
  
  <p>Note that the provider added the following part</p>
  
  <pre class="lang-none prettyprint-override"><code>%3Cdiv%20style=%22%20background-color:#; font-size: px;"&gt;&lt;div class="trop"&gt;&lt;strong&gt;Magnetická &lt;/strong&gt;kostka&lt;a href="http://unimagnet.cz/20-k-d5-neocube-216kusu.html" title="NeoCube"&gt;NeoCube&lt;/a&gt; na prodej&lt;/div&gt;&lt;/div&gt;
  </code></pre>
  
  <p>Is there anything I can do?</p>
