This morning, when I checked this blog I am a bit surprised to know that all categories and tags are not shown. It’s disappeared. Important to note that I’ve not done anything (upgrading or something like that) to this blog during this past 12 hours. I then contact my hosting provider concerning this thing assuming that the problem might come from the server.
While waiting for the answer from my hosting, I search about it in wordpress forum. It turns out that the problem has taken place many times before. Take a look at the following complains:
From Carpathia
…there was no upgrade done and am using v2.5.
Earlier this week “No categories.” appeared where the any actual category links had been before.
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 thought it was fixed after deactivating all plugins and the categories reappeared. As of yesterday, I am having the same problem again.
From Marvicbiz:
I’m experiencing the same problem with our Dutch flooring website – it’s a new installation (WP 2.6.2) and I haven’t run an upgrade.
One the web pages (right sidebar), the categories show “No Categories” while the tags are listed in the tag cloud (in the footer) but if you click on it, it says there are no posts.
When I log into admin, there are no tags or categories, not even on the posts themselves.
The Cause and Solution (?)
Miladinoski in this thread says it’s something to do with phpMyAdmin of a particular hosting is down. If it’s correct, the problem is with the hosting provider:
…I have the same problem with disappearing categories of WordPress. This is connected to phpMyAdmin falling down and not working, and that has happened 6 times for the ~3 weeks I’m hosted here, ‘cmmon guys what’s so wrong with your servers, phpmyadmin is almost 30% of the time not working and WordPress’s plugins are connected to the mySQL database and when it’s not working, they’re not working properly either (I can’t upload content, I can’t auto-upgrade plugins, some plugins don’t work, categories dissappear if they have been edited during the downtime of phpmyadmin and they come back after it’s fixed). At me, phpMyAdmin is down from yesterday, I submitted a ticket but it still isn’t resolved and I am very nerved because of that, I want my site to work at least 90% of the time as it should, I’m facing problems a lot of time I have been here, and I don’t know why there are so much problems which disappear and reappear the next day or 2 days after they have been fixed.
Anyone has the better answer?
waw, good info about wordpress’s blog
If that’s true the case, then WordPress wouldn’t be SE Friendly anymore. That means that we’d lose chance to get listed in top 10 Google SERP. Are you sure mas Fatih that those categories and tags would be disappeared for good?
#Now, the categories and tags show up again. it’s after the hosting provider fix things. I think the problem is on phpmyadmin / mysql. i’m not sure, though.
I hope I don’t face those problems, because those are very complicated for me. But, thanks for sharing the letter of complain to hosting server, it will be my reference for me. Thanks anyway.
Thanks for this post. I upgraded to 2.6 and had the same problem. I’m not a programmer, so this was very helpful. I still can’t fix my links and Blogroll – those categories won’t let me edit them, but the rest work.
