title: Error : [an error occurred while processing this directive] and regular expression confusion
body: <p>I have downloaded a website using ftp , when I test the site in my host , it shows the error </p>
  
  <p><code>[an error occurred while processing this directive]</code></p>
  
  <p>You can check this error here <a href="http://www.excoflare.com/dev2011/amplitechnic/" rel="nofollow">http://www.excoflare.com/dev2011/amplitechnic/</a></p>
  
  <p>Also, I am struggle to get a regular expression for a valid floating point number . I used this one :</p>
  
  <p><code>expression: "if (VAL.match(/^[0-9]*\.?[0-9]/)) return true; else return false;",</code></p>
  
  <p>But the above expression returns true even if I write say <code>1.x</code> ?</p>
  
  <p>Sorry I put the questions together.</p>
