title: Content Security Policy not allowing form submission
body: <p>Please I need assistance here.
  I have a form to submit to another url but when I try to submit it, it refuses to submit and I was checking my console.</p>
  
  <p>On Chrome, I see the following errors</p>
  
  <blockquote>
    <p>resources2.aspx?HCCID=75694719&amp;culture=en-US&amp;mlcv=3006&amp;template=5:7 Refused to load the image '<a href="https://s4.mylivechat.com/livechat2/images/sprite.png" rel="noreferrer">https://s4.mylivechat.com/livechat2/images/sprite.png</a>' because it violates the following Content Security Policy directive: "img-src 'self' data:".</p>
    
    <p>Refused to send form data to '<a href="https://cipg.stanbicibtcbank.com/MerchantServices/MakePayment.aspx" rel="noreferrer">https://cipg.stanbicibtcbank.com/MerchantServices/MakePayment.aspx</a>' because it violates the following Content Security Policy directive: "form-action 'self'".</p>
  </blockquote>
  
  <p>and on Mozilla Firefox I see the following:</p>
  
  <blockquote>
    <p>Content Security Policy: The page’s settings blocked the loading of a resource at <a href="https://s4.mylivechat.com/livechat2/images/sprite.png" rel="noreferrer">https://s4.mylivechat.com/livechat2/images/sprite.png</a> (“img-src <a href="http://smehelp.themarketplace.ng" rel="noreferrer">http://smehelp.themarketplace.ng</a> data:”)</p>
    
    <p>Content Security Policy: The page’s settings blocked the loading of a resource at <a href="http://smehelp.themarketplace.ng/purchase/summary" rel="noreferrer">http://smehelp.themarketplace.ng/purchase/summary</a> (“form-action 'self'”).</p>
  </blockquote>
  
  <p>Checking around the web for solution, I have added the following to my page header</p>
  
  <pre><code>        &lt;meta http-equiv="Content-Security-Policy" content="form-action 'self'"&gt;
  </code></pre>
  
  <p>but the problem still persists. </p>
  
  <p>This results in the fact that I am not able to submit my forms. Earlier, the forms used to get submitted, but I just tried it today and observed this error.</p>
  
  <p>I am running on Google Chrome Version 55.0.2883.95 (64-bit) on a MAC OS.</p>
  
  <p>I will appreciate any suggestion to solve this issue as soon as possible. </p>
  
  <p>Thank you</p>
