 * Hello! I use your theme but are constantly faced with the problem: many plugins
   do not work correctly. I wrote the author of one of the broken plugins and he
   replied:
 * > Hello.
   >  You have a problem in your theme or installed plugins, it include jquery
   > library 2 times, you can look into your web page source code, first one – around
   > 165 line: <script type=’text/javascript’ src=’[http://novaya-gatchina.ru/wp-includes/js/jquery/jquery.js?ver=1.11.3′></script&gt](http://novaya-gatchina.ru/wp-includes/js/jquery/jquery.js?ver=1.11.3′></script&gt);
   > and this is correct adding jquery to WordPress theme, and second one around
   > line 254: <script type=”text/javascript” src=”[http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js”></script&gt](http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js”></script&gt);
   > and this is not correct, as this library should be included from your WordPress
   > site, and also – there are no need to include one and same library 2 times –
   > that’s why you have javascript errors and conflicts on your site. Ask you theme
   > developer to fix this (use only first jquery connection) – and I think all 
   > functionality on your site should start working fine, including our plugin.
 * I don’t really understand English, therefore gave you the entire message. Could
   you make changes to the theme that I have earned the plugins?
