title: Remote svn HEAD revision is lower than my local HEAD revision
body: <p>Something happened to my remote SVN server and the last revision now is lower than my local revision, something like remote HEAD=160, local HEAD=266.</p>
  
  <p>I'm having trouble committing my higher version to the remote SVN, the error it displays is :</p>
  
  <pre><code>svn: E200014: Commit failed (details follow):    
  svn: E200014: Base checksum mismatch on '/trunk/.../detail.tt':
         expected:  3a404f9d1e0bfea1f408dabaa9186dfc
           actual:  90ca3254bb5fe9103f00ab289a5a5390
  </code></pre>
  
  <p>What I should do to commit my last version to the server? I have working copies of this project in production, and I think if I do a "svn update" now the project will break.</p>
  
  <p>Thanks!</p>
