We were testing our newly implemented modal popup for a login functionality. It was working pretty good in Firefox, Opera, and Chrome but not in IE8. When attempts to login by clicking on a login link the login modal was not appearing in IE8. Firebug said nothing, but jquery-1.7.2.min.js in IE showed the following error:

Message: Invalid argument.
Line: 4
Char: 190
Code: 0
URI: http:// example.com/files/js/js_05f008a1c47b8161d7e4a8e6bbff1b3f_0.js

The referred line is as follows:

this.parentNode.insertBefore( a, this.nextSibling );

The surrounding script is as follows:

after:function() {
  if (this[0]&&this[0].parentNode) {
    return this.domManip(arguments,!1,function(a) {
      this.parentNode.insertBefore(a,this.nextSibling);
    });
  }
  if (arguments.length) {
    var a=this.pushStack(this,"after",arguments);
    a.push.apply(a,f.clean(arguments));
    return a;
  }	
}

Here’s how to deal (how we dealt with) this issue:

First of all, when you identify some js error in IE be sure that it is because of violating the standards. To start off, just check for HTML errors and fix them one by one.

All you had to do in this case was:

  1. Perform HTML Validation using http://validator.w3.org/

    Check for HTML errors. For details about the most common errors found during xhtml validation, refer this.

  2. Correct the listed HTML Errors one by one.

Try the same if you are facing the same issue. That should pretty much solve this one.

If that does not seem to do the job for you, just put in a comment below. We’ll try our best to help.

How can I fix this? Thanks, Sean webmaster access_time 25 May 2020 - 09:42 In reply to Icon doesn't show by Sean (not verified) What do you see when you view the source? Search for stumblethis_button and you should be able to see the code for the image and the URL. Then you should be able to troubleshoot from there.

Most webmasters do not realize this, but a lot of the content on lot of websites can be accessed from multiple URLs. A simple example would be where www.example.com and example.com leads to the same page. This is a fatal mistake in Search Engine Optimization and search engines penalize you for duplicate content. The correct configuration would be where the above two urls will lead you to the same page but example.com will redirect you to www.example.com with a 301 (Moved permanently) status which will not result in search engines penalizing the page. It is very easy to configure 301 redirects using Apache .htaccess file and the process is the same for a Drupal installation also.

I'm trying to make example.com show as www.example.com, and I'm running into difficulties. I'm on Apache 2.0 and using the following lines in my httpd.conf file: RewriteEngine on RewriteCond %{HTTP_HOST} ^xxxxxxxxxx\.com$ [NC] RewriteRule ^(.*)$ http://www.xxxxxxxxxx.com/$1 [L,R=301] When I go to http://xxxxxxxxxx.com, I get http://www.xxxxxxxxxx.com (as expected). However, when I go to http://xxxxxxxxxx.com/node/1 (it's a Drupal site), I get a 404 thrown and the URL changes to xxxxxxxxxx.com/var/www/drupal/node/1. Same thing with www.xxxxxxxxxx.com/node/1. Any suggestions? I want to run without Drupal's .htaccess file (instead incorporating these calls into my httpd.conf file). webmaster access_time 25 May 2020 - 09:42 In reply to Rewrite including filesystem path by Anonymous (not verified) I think the problem is with the base path which results in the redirection to /var/www/ part. The best approach I would think is to start with drupal htaccess and then strip out parts and move to httpd SNVC (not verified) access_time 25 May 2020 - 09:42 This is definitely a good guide. Thanks for this. wellyson access_time 25 May 2020 - 09:42 This is really nice and helpful. Add new comment
