Title: Debugger Error causing IE9 Issue Last modified: August 24, 2016 --- # Debugger Error causing IE9 Issue * [gatehousedesign](https://wordpress.org/support/users/gatehousedesign/) * (@gatehousedesign) * [11 years, 1 month ago](https://wordpress.org/support/topic/debugger-error-causing-ie9-issue/) * Hi there, * Thanks for an amazing plugin. Everything has worked perfectly up until now when I encountered an error that is affecting IE9 only. Here’s what happened: * – Using Be theme v6.5 with a child theme and your plugin. All working perfectly on IE9,10,11 FF, Chrome, Safari. * – I upgraded the Be theme parent and other plugins after the recent security patch alert and when I tested the site I saw a layout bug in IE9 on the homepage and the PDF icons weren’t showing up on the docs pages. * The debugger in IE dev tools highlighted “index” as being undefined in mtli-str- replace-min.js?ver=3.1.0. When I deactivated MimeTypes Link Icons plugin the layout bug went away. * I reactivated the plugin in the hopes that you will be able to reproduce this in the IE dev tools debugger and that there will be a simple fix. * I hope you can help. We are due to launch on Monday but we need the icons to be working and the IE9 layout. I really hope we can use your plugin as it’s been great for our purposes. * Thank you so much. * GWD * [https://wordpress.org/plugins/mimetypes-link-icons/](https://wordpress.org/plugins/mimetypes-link-icons/) Viewing 9 replies - 1 through 9 (of 9 total) * Thread Starter [gatehousedesign](https://wordpress.org/support/users/gatehousedesign/) * (@gatehousedesign) * [11 years, 1 month ago](https://wordpress.org/support/topic/debugger-error-causing-ie9-issue/#post-6060910) * I was able to copy the error from Firebug in case that helps: ReferenceError: index is not defined [http://gatehouse-design.com/bostonpartners/wp-content/plugins/mimetypes-link-icons/js/mtli-str-replace.min.js?ver=3.1.0](http://gatehouse-design.com/bostonpartners/wp-content/plugins/mimetypes-link-icons/js/mtli-str-replace.min.js?ver=3.1.0) Line 2 * Thread Starter [gatehousedesign](https://wordpress.org/support/users/gatehousedesign/) * (@gatehousedesign) * [11 years, 1 month ago](https://wordpress.org/support/topic/debugger-error-causing-ie9-issue/#post-6060914) * Another update: the IE9 layout bug was my fault. I had a div nested inside an anchor tag in the sidebar. That was causing the issue. As soon as I fixed that the homepage loaded correctly in IE9. Phew and sorry. * However, that js error is still there in the debugger and if a fix for that would get the file icons to show up in IE9 then I would be thrilled. * Sorry for the fire drill on the home page layout. * I hope you can help me get the icons working in IE9 though. * Thanks! * GWD * Thread Starter [gatehousedesign](https://wordpress.org/support/users/gatehousedesign/) * (@gatehousedesign) * [11 years, 1 month ago](https://wordpress.org/support/topic/debugger-error-causing-ie9-issue/#post-6060981) * Another update: turning off async js in settings gets the icons back on my documents page in IE9. * However, the error on the homepage layout in IE9 persists when this plugin is activated. I tested again with the async settings updated and when the plugin is deactivated IE9 looks fine, when it’s activated it’s broken – but just that page. * Plugin Contributor [Juliette Reinders Folmer](https://wordpress.org/support/users/jrf/) * (@jrf) * [11 years, 1 month ago](https://wordpress.org/support/topic/debugger-error-causing-ie9-issue/#post-6061023) * As far as I can see – this has to do with the CSS of your theme. * I can see ‘style=”background-image: none;”‘ on the Press Release PDF link on the homepage, which effectively cancels the showing of the MTLI icon. * Also for a reason that for me is completely unclear, the ‘mtli_attachment’ class has not been added to that same link, which effectively means that even if you remove the element style I mentioned above, you would end up with a repeating background image instead of the icon just once. * Considering you are using MTLI on the homepage only in a widget – you may want to read the FAQ section on _‘I want to have the mimetype icons for a content area which is outside of the loop (a sidebar for instance). Can I?’_. * Thread Starter [gatehousedesign](https://wordpress.org/support/users/gatehousedesign/) * (@gatehousedesign) * [11 years, 1 month ago](https://wordpress.org/support/topic/debugger-error-causing-ie9-issue/#post-6061035) * Thanks jrf, * The issue on the homepage isn’t to do with the icons – I don’t want icons in the sidebar on the homepage. It’s a layout bug in IE9 that’s causing the sidebar to stretch the width of the page and various other bits of weirdness. * When the plugin is activated the bug shows in IE9. When it’s deactivated the homepage displays perfectly in IE9. * Thanks for looking at it. * Thread Starter [gatehousedesign](https://wordpress.org/support/users/gatehousedesign/) * (@gatehousedesign) * [11 years, 1 month ago](https://wordpress.org/support/topic/debugger-error-causing-ie9-issue/#post-6061037) * I’ve narrowed it down further to a conflict with Slider Revolution. If I deactivate that plugin and MTLI is activated the homepage loads fine in IE9 but without the slider. * Will keep working on how to resolve this conflict. Any ideas, let me know. Thanks! * Plugin Contributor [Juliette Reinders Folmer](https://wordpress.org/support/users/jrf/) * (@jrf) * [11 years, 1 month ago](https://wordpress.org/support/topic/debugger-error-causing-ie9-issue/#post-6061038) * So what is the problem ? and does it have anything to do with MTLI at all ? If not, please mark this issue as resolved. * When I test in IE9, I do get a js error, but one which has nothing to do with MTLI: * SCRIPT5007: Unable to get value of the property ‘childNodes’: object is null or undefined wp-emoji-release.min.js?ver=4.2, line 2 character 172 * I also see that the layout is strange, but don’t see how that would have anything to do with MTLI. * Thread Starter [gatehousedesign](https://wordpress.org/support/users/gatehousedesign/) * (@gatehousedesign) * [11 years, 1 month ago](https://wordpress.org/support/topic/debugger-error-causing-ie9-issue/#post-6061041) * The problem is a conflict with the slider revolution plugin on the homepage causing incorrect layout – in IE9 only. * Thread Starter [gatehousedesign](https://wordpress.org/support/users/gatehousedesign/) * (@gatehousedesign) * [11 years, 1 month ago](https://wordpress.org/support/topic/debugger-error-causing-ie9-issue/#post-6061057) * I added this conditional (if is_front_page) to my child theme functions.php * ``` function remove_unwanted_scripts(){ if(is_front_page()){ wp_dequeue_script('mimetypes-link-icons'); wp_dequeue_style('mimetypes-link-icons'); } } add_action( 'wp_enqueue_scripts', 'remove_unwanted_scripts', 100 ); ``` * This just removes the MTLI script and styles from the homepage where the conflict with Slider Revolution was causing a layout bug in IE9. * All good for now. Would be a great backend feature to if users could exclude certain pages from getting the script. * Thanks for your help jrf.
