Yoast and Standard theme: Fatal error
-
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
orfunction_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The breadcrumbs class in our plugin is maintained, whereas the breadcrumbs class shipping with your theme is probably out of date.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
orfunction_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.Source: http://kb.yoast.com/article/97-cannot-redeclare-yoast_breadcrumb-error

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."

Error after scanning with browseo.net
Good day! I have done a scan on my site with browseo.net ( and a few other similar scanners ) and got the mess seen in the screenshot. I've tried deleting all the files in the website folder, replace it with a single image file, but it still shows the same error. What could this mean and should i be worried? P.S Found my answer after contacting the helpful support of browseo.net : It took me some time to figure out what was going on, but it seems as if you are mixing content types. Browsers are quite smart when it comes to interpreting the contents, so they are much more forgiving than we are. Browseo crawls your website and detects that you are setting utf-8 as part of the meta information. By doing so, it converts the content in a different character encoding then what they are supposed to be. In a quick test, I tried to fetch the content type based on the response object, but without any success. So I am suspecting that in reality your content is not utf-8 encoded when you parse it into joomla. The wrong character type is then carried over for the body (which explains why we can still read the header information). All of this explains the error. In order for it to work in browseo, you’d have to set the content type correctly, or convert your own content into utf-8 before parsing. It may be that you are either storing this incorrectly in the database (check your db settings for a different content type other than utf-8) or that other settings are a bit messed up. The good news is, that google is probably interpreting your websites correctly, so you won’t be punished for this, but perhaps something to look into… From Paul Piper VKNNnAL.png?1

What should I do with URLs that cause site map errors?
Hi Mozzers, I have a client who uses an important customer database and offers gift cards via https://clients.mindbodyonline.com located within the navigation which causes sitemap errors whenever it is submitted since domain is different. Should I ask to remove those links from navigation? if so where can I relocate those links? If not what should I do to have a site map without any errors? Thanks! 1n16jlL.png

4XX Errors - Adding %5c%5c to Links
Hi all 😃 Hope someone can help me with this. The internal links on my hubby's business site occasionally break and add %5c%5c%5c endlessly to the end of the url - like this: site.com/about/hours-of-operation/\\\\\\\\% I cannot for the life of me figure out why it is doing this and while it has happened to me from time to time, I can't recreate it. My crawl diagnostics here in my SEOMox campaign show 19-20 urls doing this - it's nuts. Any insight? Thank you!! Jennifer ~PotPieGirl

Fixing Missing MetaTag Errors
Hey all, I just had a crawl test done on my site(created using wordpress) and I received a ton of missing meta tag descriptions to fix. The odd thing is though I use "All in One" SEO Tool and the actual pages or posts on the site do have meta tag descriptions, however I noticed for every post an RSS Feed is being automatically generated and this Feed is the link missing the meta tag descriptions. Most of the errors display "Comments on" with a /feed in the end of the url. I am totally clueless on how to resolve these errors as I havent installed any WP plugins that generate feeds automatically. Has anyone encountered this problem before or know how to fix this?? The site url is http:// GovernmentGrantsAustralia . org I have left spaces above to avoid being a link dropper 🙂 Would really appreciate if anyone can help! FYI: I just found this link after digging through all the Q&A history, however I tried it and am not sure if it has worked as I still see the errors on my SEOmoz report. The link is:

404 Error on Spider Emulators
I recently began working at a company called Uncommon Goods. I ran a few different spider emulators on our homepage (uncommongoods.com) and I saw a 404 Error on SEO-browser.com as well as URL errors on Summit Media's emulator and SEOMoz's crawler. It seems there is a serious problem here. How is this affecting our site from an SEO standpoint? What are the repercussions? Also, I know we have a lot of javascript on our homepage..is this causing the 404? Any advice would be much appreciated. Thanks! -Zack
