Yoast and Standard theme: Fatal error

[DonnaDuncan]

Hi all-

A client has tried installing Yoast on her site and received at fatal error (below). She's been able to restore her site and get it functioning again, but I'm wondering if there's a work around so we can use the plugin. It's a Wordpress site using the Standard Theme.

I've searched the forums (and here!) and haven't found anything helpful yet. Do you have any suggestions?

Thanks!

Thanks for your research Kevin. I saw the same thing. Was looking for work-arounds actually.

Thanks.

Hi,

It's not a big job to implement, best practice is to use a child theme however you could hook it in the theme functions file.

Hi DeanAndrews.

Thanks for your response.

The client has renamed the offending wordpress-seo plugin directory to wordpress-seo-old and that restored the site immediately. Can we just leave it that way, reactivate the plugin, and move forward from there or will other problems arise?

If we "wrap the class and functions" as you suggest, is it a large effort? Will it impede our upgrade ability should the Standard Theme release an upgrade?

Just trying to understand all our options and am very appreciative of your help.

From Yoast KB:

If you're getting an error that looks like this:

Cannot redeclare yoast_breadcrumb() (previously declared in /hom/require/public_html/wp-content/plugins/wordpress-seo/inc/wpseo-functions.php:96) in <path></path> 

Your theme or another plugin is including our  breadcrumbs class, and not properly wrapping it in class_exists or function_exists wrappers. The <path>part of the error above should normally point you at either a themes or plugins directory, telling you which plugin is the culprit.</path>

The breadcrumbs class in our plugin is maintained, whereas the breadcrumbs class shipping with your theme is probably out of date. So check with the creator of your theme and send them to this page.

You should wrap the class and functions in  class_exists or function_exists wrappers. Or, even better, you shouldn't include it at all and just tell people to install our WordPress SEO plugin and use the breadcrumbs provided by our plugin as those are far more up to date and actually work with custom post types, custom post type archives, etc.

Do you have the plugin Wordpress SEO installed? Possible explanation from a user at stackoverflow:

"You have the plugin Wordpress SEO installed which has breadcrumbs included. It looks like you cannot install the breadcrumb plugin also. Use the breadcrumb feature included in Wordpress SEO plugin."
