Categories disappear (11 posts)

    Sometimes when I load my site I get this message instead of any actual category links, "No categories." Other times, they're there. Also, when I go to manage my posts, no categories are displayed but when I actually click edit, category check boxes are ticked. Can anybody tell me what's going on?

    Ditto. I have the exact same problem. I am not sure when it happened. A while ago I upgraded to 2.3.3 but I believe the problem did not exist then. Later I was looking in the Manage->Categories section and there were no categories at all. When I click Edit on a post, I do see all the categories as checkboxes in the upper-right "Category" panel.

    Additionally, it may be helpful to note that, when I go to
    Manage->Posts, all Posts are marked as "Uncategorized" while if I do click on any given Post the Categories panel does properly indicate the categories that it belongs to.

    However, curiously the sub-categories that my old articles used to belong to have disappear altogether. They are nowhere to be seen.

    I'm using version 2.3.3 as well, and my site is experiencing the same problem.

    The post shows the appropriate categories ticked, but the front-end lists no categories, as does the back-end category manager.

    When I go to add the categories that disappeared, magically, the post count per topic reflects the actual number. Then I refresh, and *poof* they disappear.

    I just noticed this. I don't know if this has anything to do with the "del.icio.us" xml-rpc posting feature.

    Same problem with my site.

    Plus: I see an error message, "Table 'clapp2_wrdp1.wp_categories' doesn't exist" for My Category Order plugin.

    Looks like a plugin problem. Removed the My Category Order plugin, updated the Fold Category plugin with new arguments. All's well now.

    Checking my bolg today I get this message instead of any actual category links, "No categories."

    When I go to manage > categories, no categories are displayed.

    When I go to Manage->Posts, all Posts are marked as "Uncategorized". When I do click on any given Post the Categories panel does properly indicate the categories that it belongs to.

    I have not upgraded recently and am using v2.5.

    Can anybody tell me what's going on?

    I am having the same problem with several blogs - no idea why..

    This seems to happen after logging in -

    Categories are there - after logging in - they are gone - recently upgraded top 2.6.2 - could this be the cause?

    no plugins runnings.

    if you add a category and it is a dupe of what was already there before - it says error - that category already exists. Yet there are no categories displayed at all.

    cats still show in sidebar on public site, but every post is labled as being in uncategoized cat..

    I have been having this issue with two websites on wordpress 2.7. The problem happens randomly, usually when someone is using one function or another in the admin side.

    The solution is often times random as well. Restarting the database sometimes fixes it (is not fixing my current issue). Sometimes it is just fixed on it's own with no real explanation.

    I have many websites that run on WP 2.7 and I will compare the taxonomy and term tables of a healthy wordpress site against the broken one and cannot find a difference.

    I wonder if the WP dev team is aware of this really frustrating issue.

    VERSIONS: WordPress 2.7 and 2.7.1; PHP version 4.4.7; MySQLversion 4.1.22-standard, Server OS - Linux. Hosting service provider: inmotionhosting.com.

    PROBLEM: Categories and Tags disappeared from the WordPress admin, and were not visible on the blog (none displayed in Posts > Categories or Posts > Manage Tags). When editing a post, I could see "Most Used" but not "All Categories." All posts had their categories changed to "Uncategorized" in both Manage > Posts and on the posts in the blog.

    I could see the Categories and Tags in the database.

    SOLUTION: Restart the MySQL Server.

    If you manage your own server, you can restart the MySQL server from the command line. I am a hosting reseller, so I could use the Web Host Manager. If this applies to you, go to your WHM, click Restart Services, then click MySQL Server. If you don't have that access, contact your hosting service provider to restart the server.

    WHAT DID NOT WORK: Deactivating all plugins. Upgrading WP (2.7 to 2.7.1, in my case).

    My research indicates that this ia a mySQL server problem, not a WordPress problem. A number of other Web posts and forums indicated that a MySQL server restart also worked in their cases.

    It remains to be seen if the problem is solved for good, but all is working as it should now.
