# Javascript No Longer Works

 * I have been using the plugin ‘Head, Footer and Post Injections’ to insert header
   info into every page.
 * Google wanted me to update some info for their Analytics and when I did, I got
   a Internal Server Error.
 * It turns out to have nothing to do with Google, but a javascript that is in each
   page. There is a map on the side of each page that has hover and click buttons.
   When I remove that javascript, the Internal Server Error goes away. But now my
   map is static and there is not an indication that clicking on a town will do 
   anything.
 * The full error message says:
 * ‘The server encoutered an internal error or misconfiguration and was unable to
   complete your request.’
 * Using PHP 7.4 FastCGI. It is shared hosting.
 * Below is the Javascript that I have been using for years:
 *     ```
       <!-- Javascript for map -->
   
       <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
       <script type="text/javascript">
       $(document).ready(function () {
         $('#nav > li > a').hover(function(){
           if ($(this).attr('class') != 'active'){
             $('#nav li ul').slideUp();
             $(this).next().slideToggle();
             $('#nav li a').removeClass('active');
             $(this).addClass('active');
           }
         });
       });
       function MM_swapImgRestore() { //v3.0
         var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
       }
       function MM_findObj(n, d) { //v4.01
         var p,i,x;  if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
           d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
         if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
         for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
         if(!x && d.getElementById) x=d.getElementById(n); return x;
       }
   
       function MM_swapImage() { //v3.0
         var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
          if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}
       }
       </script>
       ```

 * JavaScript does not cause server-side errors because it runs in the visitor’s
   browser. So the cause must be something else.
 * How do you insert this JavaScript code into your page? Do you use a plugin for
   this – which one? Or do you edit a template file?
 * Also a look into the error log of your hosting would be interesting. There you
   should be able to see the exact cause of the error. Alternatively, you could 
   also activate the debug mode in WordPress as described here: [https://wordpress.org/support/article/debugging-in-wordpress/](https://wordpress.org/support/article/debugging-in-wordpress/)

 * Thank you for your response.
 * I use the plugin ‘Head, Footer and Post Injections’.
    [https://www.satollo.net/plugins/header-footer](https://www.satollo.net/plugins/header-footer)
 * I believe I also tried another plugin with the same result, but I am not sure
   which one it was.
 * I will look into the error log post what I see. And read through the debugging
   link you provided.

 * I decided to go into the Theme and edit the header.php directly. I inserted the
   header into the Theme header.php and now the JavaScript is working properly and
   there are no errors.
 * Not sure why I was getting the ‘Internal Service Error’ while using the plugin‘
   Head, Footer and Post Injections’ for the exact same Javascript, but the map 
   is now working properly on all my pages.
 * Thank you for your help.

 * Changing theme files is not recommended. These will be overwritten with the next
   update. If you do this, I would recommend a child theme: [https://developer.wordpress.org/themes/advanced-topics/child-themes/](https://developer.wordpress.org/themes/advanced-topics/child-themes/)
 * If you have any questions about the plugin you are using, especially if you think
   it is not working properly, you should contact their support: [https://wordpress.org/support/plugin/header-footer/](https://wordpress.org/support/plugin/header-footer/)

 * Thanks. I figured I would have to repeat the process with every update. So I 
   kept the header info so I could just copy and paste.
 * I will follow up with the plug-in developer though.

 * The plug-in support said:
 * “If you have an error while saving, almost surely is a provider filter blocking
   the kind of content you’re saving. Ask them for such a filter, could be by mod_secure.”
 * I contacted the web hosting tech support. They told me:
 * “…..effectively your IP was being
    blocked by mod-security. I whitelisted the
   rules and ran a config on the Apache service to refresh the server. The changes
   have been enforced.”
 * Not sure why my IP was being blocked, and why this was the only issue I was having,
   but it all works now.
 * Thanks for your help.
