Title: [Plugin: WP Captcha-Free] Cannot post IE8 Last modified: August 19, 2016 --- # [Plugin: WP Captcha-Free] Cannot post IE8 * Resolved [MyrddinDE](https://wordpress.org/support/users/myrddinde/) * (@myrddinde) * [15 years, 9 months ago](https://wordpress.org/support/topic/plugin-wp-captcha-free-cannot-post-ie8/) * Hello, * I recently upgraded to w3 total cache and my site is running quite fast until I tried to reactivate this plugin. I really love the idea of not bother posters additional hurdles and had been using WP Captcah Free on my previous blog successfuly. * Anyway, it seems to work well when trying to comment in firefox. But once use my Internet Explorer 8 I get this error: * Benutzer-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Trident/4.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.5.30729; .NET CLR 3.0.30729; .NET4.0C; Creative AutoUpdate v1.40.01) Zeitstempel: Mon, 30 Aug 2010 07:05:14 UTC * Meldung: ‘document.getElementById(…)’ ist Null oder kein Objekt Zeile: 2 Zeichen: 509 Code: 0 * on URL: [http://www.myrddin.de/2010/08/20/total-gold-acquired-august-2010/](http://www.myrddin.de/2010/08/20/total-gold-acquired-august-2010/) * Can you have a look at it?

Try this one instead (at the very least the developer visits these forums every day): * [http://wordpress.org/extend/plugins/si-captcha-for-wordpress/](http://wordpress.org/extend/plugins/si-captcha-for-wordpress/) * Thread Starter [MyrddinDE](https://wordpress.org/support/users/myrddinde/) * (@myrddinde) * [15 years, 9 months ago](https://wordpress.org/support/topic/plugin-wp-captcha-free-cannot-post-ie8/#post-1648974) * Thanks for the quick reply, I’ll have a look at it. * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [15 years, 9 months ago](https://wordpress.org/support/topic/plugin-wp-captcha-free-cannot-post-ie8/#post-1648977) * You’re welcome! * Thread Starter [MyrddinDE](https://wordpress.org/support/users/myrddinde/) * (@myrddinde) * [15 years, 9 months ago](https://wordpress.org/support/topic/plugin-wp-captcha-free-cannot-post-ie8/#post-1649019) * It seems to be well working, but the real advantage of WP Captcha-Free was that you did not bother your commenters with that kind of stuff as it worked nice in the background. * But I guess it is not big usse for them to do … I had 644 spam comments the 2 days I left WP Captcha-Free turned off 😀 * Thanks for the advice. * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [15 years, 9 months ago](https://wordpress.org/support/topic/plugin-wp-captcha-free-cannot-post-ie8/#post-1649076) * If you’re looking for something that won’t impact your readers, try Akismet ( it should have come with WP). * Thread Starter [MyrddinDE](https://wordpress.org/support/users/myrddinde/) * (@myrddinde) * [15 years, 9 months ago](https://wordpress.org/support/topic/plugin-wp-captcha-free-cannot-post-ie8/#post-1649239) * Well, the Idea was to avoid having spam even get into the database and not to bother visitors with it. * I found the kind of addon I was looking for today: * **NoSpamNX** – it adds some hidden form fields and spam bots will touch these fields which will block the comment. Easy, no extra gx, javascript or anything. works like a charm, even with cache.
