How to fix Internet Explorer 8 messing up WordPress themes

Here’s a mini-plugin (single line of code actually) that will prevent the new IE8 (aka Internet Explorer 8 ) from messing up your carefully crafted WordPress or bbPress design.

<?php if (strpos($_SERVER['HTTP_USER_AGENT'],"MSIE 8")) {
header("X-UA-Compatible: IE=7");} ?>

Make a mini-plugin out of it and activate.
(you might be able to put it into functions.php if that executes before other data is sent but I am uncertain – for the extremely lazy you could in theory put it as the very very first line of header.php in your template)

I also have it listed as a more formal plugin over here

For those that don’t want to install IE8 permanently to just test their webpages, this version will run in it’s own virtual box so it doesn’t affect the rest of your system:
http://start-o.xenocode.com/layers/ie8/8-0-0-0__2/ie8.exe
There’s no install, it just runs instantly from that one file.

    How to make a mini plugin?
    I have try to copy-paste that code to dreamweaver blank php file and save it. Then I upload to my wordpress blog, but the php file is not detected. What should I do?
    Thank’s

  6. Anthony you can probably just copy that line into a file called
    functions.php
    and put it into your wordpress theme folder.

    Thank you so much for this tip. I was getting upset. I just installed Explorer 8 and it was rendering my Blog in a weird way. It rendered the text and took a lot of time to display pictures or the header. After putting that code in the functions.php file, it loads as before.

    Greetings,
    Alex.

    Is there a fix for the new FireFox?? I just noticed it render the page in a weird way too in the new 3.0.10 Firefox…

    It would be great to know what exactly is causing that problem.. something in the style css, not sure..

    it loads the page in a very weird way…

    Thanks.

  10. your solution worked perfect!! Thank you so much!

    I just finished and tested my site for IE6, IE7, Safari, and FF on Mac & PC and worked out whatever little bugs I had with IE7. Then I tested on IE8 and just about flipped when everything rendered all weird…

    I hate internet exploder… each version just keeps getting worse **sigh** – the world needs to move to Firefox or any other standards compliant browser!!

  11. My site receives millions of hits each month and I’ve been soooo frustrated with the way it looks in IE8. I had to put this code into my header.php because I already had a function.php file. AND IT WORKED!!!! THANK YOU THANK YOU THANK YOU THANK YOU!!! If you’re ever in Vegas, email me, and I’ll get you a beer as well!! :)

    i’ve used your code, and although it works, i can no longer log into wordpress anymore. is there something i can fix so that i can log into wordpress again? thanks!

    • That error often means you’ve simply put whitespace before the <?php
      or after the ?> (either new lines or spaces).

      Make sure you have nothing before or after the start and end of the plugin code.

    hi molly, I receive the same error message!

    It is perfectly normal when I check the site with chrome, however with ie, it is messed up!

    January 11, 2011 at 8:15 am

  22. Just after using your code I was unable to log back in this is what happens when I try on any browser now:

    Warning: Cannot modify header information – headers already sent by (output started at /home/content/r/e/u/reubenroyce/html/wp-content/themes/mts-journey/functions.php:4) in /home/content/r/e/u/reubenroyce/html/wp-includes/pluggable.php on line 890

    How do I fix that? Please help.

      • So I havie no access to the server the blog is now hosted on. How do I fix it when I can not access it or log into it?

        January 21, 2011 at 4:50 pm

    • If you cannot access your blog you should delete (or rename) the plugin via FTP access.

      Assuming it’s the plugin that caused the problem, as soon as it’s deleted, it should return to normal.

      Even if you do not have FTP access, many web hosting control panels give you simulated file access to delete or rename files via your browser.

    Thank you! Thank you! THANK YOU! A new WordPress site I’m building (1st time WordPress user) was moving like a slug on IE8. I don’t even know enough about WP yet to get into template header. But I posted your code into the top of my “Home” page and presto, everything is just great! Shame that I couldn’t find anything on either the WordPress site or Microsoft’s — so again, Thank You Very Much!!! :)

    May 1, 2011 at 12:23 am

  29. I tried by editing the style.css file, but without success.
    Thanks for the solution !

    You are a lifesaver! I hired freelancers that even couldn’t figure this out.

    July 4, 2011 at 10:57 am

  32. Doesn’t do it for me unfortunately.
    Getting this 3 columns blog show properly in IE9 or Opera is a nightmare.
    I had the template made with Artisteer, but I have been forced to switch to a ready made one and customise it. I’d have rather used my own design. But in these 2 browsers one entire widget column simply doesn’t show. Have the same problem using sufusion (ready made popular template).
    If anyone found a solution to this I would very much appreciate a reply.

    Hi!

    I just have problems with ie 6(what i know about). Do you have any solutions for that browser?

    July 21, 2011 at 8:25 pm

  34. I just spent something like 5 hours trying to figure this out. It was working on the front page for some reason, but no other pages. But this fixed it, and I really don’t understand why it did.
    Thanks though!!

  44. Hi CK;
    I´m using your mini-plugin following your instructions and I can´t find the solution for prevent the changes between IE8 and wordpress.
    I would like a reply with a post or an mail.
    Thank you very much for your kindness.

    • Keep in mind this plugin was meant for when IE8 was released to make a theme that worked with IE7 keep working with IE8

      It’s not meant to address the numerous problems in general that IE8 has rendering a theme compared to Chrome or Firefox or Safari.
