wordpress - W3C Validator doesn't load the actual sources -

I wanted to use the W3C validator to customize my Wordpress blog on the main page, he claimed 28 errors. For one of them was the following:

Line 28, column 53: The end tag has been omitted for "meta", but omitip was not specified

 < Code> & lt; Meta name = "DC.Creator" content = "Raffel Harman" & gt;    
 So I fixed it and clicked Modify again. Yet the verifier says that this error still exists. But if I look at the browser source code window from my web browser, then I can see that the changes can be successful. If I check "Show Source" in the options of W3C validation and reload my site, then I can see that the source code of my site uses the verifier, without change / Is old  
 To explain to me why the W3C validator did not recognize my changes? If you do not want to see yourself, then my blog's URL.   
 
 
 I know this is a little old, but I'm on the exact same issue, I found this thread , And then I found an easy solution.  
  issue:   
 I fixed some things that I told me about verification, clicked the refinance button, and this same error and source code Shows as I did before making changes.  
 Some caching is definitely happening somewhere. I'm also using WordPress with the WCTC plugin, but the only browser cache setting enabled by me, is the last-modified header set.  
  Solution:   
 I have worked with other services on similar issues before, and here's a simple solution ...  
 Add "? X = 1" at the end of the URL, increase the value every time you want to verify again, it leaves the cache because it is a different URL. (If you already have a question mark in the URL, use "& amp; x = 1". If you already have "x =" in the URL then use anything like "y =". For example ...   
 If you want to validate the home page here:  
  http : //mydomain.com/   
 ... You can verify it again:  
  http://mydomain.com/?x = 1   
 ... and validate it again:  
  http://mydomain.com/?x=2  < / P> 
 ... and so on.  
 If you want to validate a dynamic page on this:  
  http://mydomain.com/mypage.php?x=123  < / P> 
 ... You can re-verify that page here:  
  http: //mydomain_com/mypage.php? X = 123 and y = 1   
 ... and validate it again:  
  http: //mydomain_com/mypage.php? X = 123? Y = 2   
 ... and so on.
