title: 'unicode' object has no attribute 'replace'
body: <p>I have been running a Django site for a couple of months now and an hour ago began receiving the following error message (about three times a minute on various pages):</p>
  
  <blockquote>
    <p>AttributeError: 'unicode' object has no attribute 'replace'</p>
  </blockquote>
  
  <p>This is happening throughout the codebase, including in Django code itself. The codebase has not changed at all for a week and has been accessed frequently during that period and the error has <em>never</em> appeared. As it stands now I am getting several every minute - but somewhat coincidentally have not received any for the past ten minutes.</p>
  
  <p>The error also appears to be reasonably sporadic in nature in that pages that error out with 500 can still load after a refresh or two.</p>
  
  <p>Does anyone know what the cause of it may be? My server has WHM/CPanel installed but I don't think it should be touching the Python installation which I performed separately, so how this error has come up out of the blue has me quite baffled.</p>
