Support » Plugin: WordPress MU Sitewide Tags Pages » Sitewide tags creating duplicate categories in tags blog

  • Resolved mbeasi


    This is an issue that’s been happening for me ever since I started using Sitewide Tags with WordPress 3.0, and I’ve just dealt with it all this time. Since I’ve never seen anyone else complain about this, I suspect it could be something I’ve done wrong, but here’s the issue:

    When posts are made in blogs other than the site’s main blog, frequently (but not *always*) they are generating duplicate categories in the main blog. For instance, if someone posts an entry with the category “License Requests,” the post is added to the tally of all those using the original “License Requests” category, but it also creates a new category with the same name. This happens over and over, not with all categories, but with specific ones repeatedly. If I don’t delete them on a weekly basis, I eventually end up with several pages worth of the same category in my list of categories on the main site. Again, this only seems to happen with certain categories, and it happens with those every time. Others seem entirely unaffected.

    It’s not a fatal issue, which is why I’ve never brought it up before, but it is a bit of a pain to maintain. Has anyone heard of this happening before? Any clue as to what’s gone wrong?

    i’m running selfhosted wordpress 3.1

    You have to be running selfhosted WP to use SWT. The change I made last weekend was only tested on WP 3.2.1, so I don’t know if it addresses the issue in 3.1.

    Go into your database admin tool and look for a row where the meta_key is global_terms_enabled. Is the meta_value a 0 or 1?

    Sorry, forgot to include the table to look in: wp_sitemeta.

    I hadn’t tested it with global_terms_enabled on. Since yours is off then that’s not the issue.

    What other plugins do you have installed? Also, when do you plan to upgrade to a more recent version of WP?

    Hi ron!

    I have no other plugins activated on that blog.. Im running sunrise domain mapping..

    Thats why im affraid of updating.. Some things may not work correctly..

    Plugin Author Ron Rennick


    I meant on the source blog of the post, network activated or installed in the mu-plugins folder.

    It doesn’t matter what plugins are active on the tags blog because that isn’t the active blog when the post is being saved. When WP does the internal blog context switch it does not load the theme or plugins of the blog it switches to.

    Well.. has 47 blogs activated.. And what plugins they run is hard to know.

    But the complete lists if it helps:

    I think you’ll have to spend a bit of time to track some the extra categories back to a specific site so that you can cut down the list of plugins a bit.

    There are probably a few you can rule out

    – Akismet – lots of people use this and it only interacts with comments
    – Custom CSS – doesn’t use taxonomies
    – Bad behavior
    – Disqus – I haven’t used this one but I assume it uses similar hooks to Akismet

    hi Ron,

    There is no extra categories on the blogs where the posts come from! The categories on the other network blogs have the same category name and slug..

    Do you mean something else?

    There is no extra categories on the blogs where the posts come from!

    I wasn’t expecting that there would be.

    If you have new extra categories show up, look at the new posts in the tags blog to determine which site the extra categories came from.

    I’m having the same problem…mostly with the same few categories. I can’t find anything unique about the blogs the posts are coming from (I’m in a school, so we’re talking all student blogs). Could the More Privacy Options plugin be the culprit?

    The plugins I have installed network-wide are:

    Viper’s Video Quicktags
    WP Smush It
    SlideShare Embeds
    More Privacy Options

    The ones I have available to the network (but not automatically activated):

    All-in-One Event Calendar Plugin
    Bad Behavior
    Breadcrumb NavXT
    Configure SMTP
    Google XML Sitemaps with Multisite support
    jQuery Collapse-O-Matic
    Login Logo
    NextGEN Gallery
    NextGEN Monoslideshow
    Optimize DB
    Post Types Order
    Slickr Flickr
    WordPress Importer
    WordPress NextGen GalleryView
    WP Events Calendar

    A-Ha! I posted to a network blog, and my tags blog made 8 copies of one of the categories.

    This particular post was assigned 9 categories and only the last category was replicated…8 replicas with 0 posts and one with the new post in it.

    Update: I was able to repeat it. It happens when a post has more than one category assigned to it. This time I assigned 4 categories to the post, and only the last one was replicated, and only once.

    Notes: doesn’t seem to replicate categories where the name starts with a number? I have 10th grade, 11th grade, etc…these don’t get replicated. If I assign 2 categories and both are non-numerical…they both get replicated.

    Conclusion I’m drawing: When there is more than one category assigned to a post, each category will be replicated…the number of times depending on the number of other categories assigned to that post. Numeric categories are not replicated.

    I hope this helps in some way! Email me at if you want me to try and explain better…

    @nearlyjen – thank you for the troubleshooting. Having a reliable process to reproduce the issue is awesome.

    Plugin Author Ron Rennick


    I tried to duplicate this and could not. I tried 3 categories, 9 categories. None of my categories start with a number.

    Are you sure you have updated to the latest development version?
