Woocommerce Primary Category Bug (Bread Crumbs)

  • Hello,

    Thank you for contacting Rank Math today.

    It seems to be working fine on our setup or do we need to follow some other steps to reproduce? Here’s a screencast:

    Assuming you are using the latest version of all the plugins and the themes (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.

    To determine that, please follow this troubleshooting guide:

    Please let us know if you find the culprit.

    Only the site admin would know and your users won’t be affected by this troubleshooting.

    Looking forward to helping you.

    Hi @pratik-d.

    Thank you for providing the screen cast. Your setup looks the same as mine.

    Yes, my plugins and themes are all running the latest versions except for Woocommerce which is on version 3.9.2

    I have now managed to get the breadcrumbs to display correctly, although I am not sure what was causing the issue I can tell you how I managed to fixed it.

    I setup a staging site and installed the “Disabled Emails” plugin (https://wordpress.org/plugins/disable-emails/). I then noticed that the issue was resolved. I disabled the “Disable Emails” plugin and the breadcrumbs are still working correctly. So I did the same thing on my live site. I installed and activated the “Disable Emails” plugin and then deleted it. That is the only thing I did to fix the issue.

    After resolving the issue, on my staging site I installed the Query Montior plugin (https://wordpress.org/plugins/query-monitor/) I have noticed for some time now that when updating plugins (maybe installing too) that RankMath generates the following database errors. Perhaps this could have been the cause of the issue in the first place?

    Here is a copy of the error log:

    INSERT INTO 'wp_rank_math_internal_meta' ('object_id', 'internal_link_count', 'external_link_count', '0')
    VALUES (18890, '0', '0', '')	
    	Unknown 	Unknown column '0' in 'field list' 	qmdb
    UPDATE 'wp_rank_math_internal_meta'
    SET 'object_id' = 18890, 'internal_link_count' = '0', 'external_link_count' = '0', '0' = ''
    WHERE 'object_id' = 18890

    Does any of this help to narrow down what it could have been?

    Thanks for the great support.


    Thanks a lot for the additional information.

    I am just glad that the issue is fixed now.

    Hey, if it isn’t too much to ask for – would you mind leaving us a review here?


    It only takes a couple of minutes but helps us tremendously.

    It would mean so much to us.

    Thank you.
