hello
i looked through a webpage on w3c validator and found that there are some errors from the x class. so its x theme related right? I have attached a screenshot of the errors i mean.

this page: http://cannadems.org/map/new-hampshire/
is there a way i could go through and fix these errors automatically? i am up to date with the theme on the website.
there is no error loading this page but our web guy told us: I apologize for this but this 500 Error is related to the website and it’s design. You are going to have to check your codes and headers as the 500 error is not Hostgator’s 500 Error but one related to your ending of headers. We did check the .htaccess and other parts of the server. The cannadems.org/wp-admin will load for your to optimize.
is this a x theme [fixable] error?
