Got “Problems After Upgrading To WordPress 3.0.1?”

How to fix or solve wordpress blogs problems since updating, or if your blog doesn’t work as usual, and make you want to downgrade to the older version of wordpress.

I have been updated this blog successfully and it went smoothly without any problems. But i am sure there are tons of wordpress blogger out there who got some troubles or problems since updating their wordpress to version 3.0 or 3+.

These problems can be caused by some plugins, and mostly because these plugins were built for older version of wordpress.


Why can plugins cause problems? This is because those plugins were not updated by the creator, so it can cause some problems while you were updating your blog.

What problems are usually happening to your blog?
1. You can’t upload images, or videos.
2. Redirect problems, your post or page suddenly redirect to some page that you don’t want.
3. Broken RSS feed.
4. Your blog is broken and has white screen.

White Screen after upgrading problem example.

How to fix this updating problems?
1. Deactivate every plugins you installed, by going to your cPanel, and rename them one by one. Refresh your blog.

2. Still not working? switch to default theme, if you can’t login to your dashboard, rename the theme you are currently using. Refresh again.

3. Still does not work? Download wordpress files again from wordpress.org and upload wp-admin and wp-includes folder. Refresh and try to see if it works.


Everytime you try the steps above, refresh and try your blog if it works, after it works again, enable and activate one by one of your plugins, to see which one can cause the problems.

If these methods above do not help, wordpress forum has helpful people. Good luck!

    I updated about six sites with no issues. You do need to deactivate the plugins before the upgrade or crazy stuff like the widgets disappear. If something crazy like that happens, I found deactivating the plugins again..going to widgets to see them safely back up..then reactivating the plugins did the trick. I think having a theme that is updated to work with 3.0 is another important consideration.

      @Melinda, That’s great tip Melinda, about deactivating all plugins before upgrading, and i do think that really will help.

      It’s always nice to hear people successfully upgraded their blogs.

      Lots of people are still using 2.9.2 and waiting for the next wordpress version.

      And i agree with the compatible theme, probably much better to switch back to default theme first before upgrading.

      Thank you for giving a tip and commenting.

      @sameh shaker, First, backup your database.

      Deactivate all plugins.

      Switch back to default theme

      Will it work?

      Let me know.

    I recently upgraded to WP3.0 but now I am receiving so many 404 errors that my hosting provider has taken the site offline 3 times this week. I added the DB caching reloaded Plugin. However, that causes a db error message and won’t allow me to post or empty spam. Wondering if I should roll back to 2.9.2?

      @Miche, I hope you have your database backed up.

      Have you tried to disable all plugins?, including cache plugins, but they usually have special uninstall process.

      If still doesnt work, switch back to default theme.

      I would not downgrade my blog, if it’s possible.

      Good luck.

      @Miche, I agree…disable every plugin. Switch to default theme, then back to the theme you use. Reinstall the plugins. I had to repeat this twice on the first site I upgraded because I installed 3.0 with the plugins activated. I don’t know why it worked the second time and not the first. Worth trying to see if it corrects it. Do you have a plugin that does something with permalinks..I would be suspicious that maybe that is causing the 404 page errors. Just another thought. Good luck!

    WP 3.0 I needed because of a Facebook clone thing. When I add or update a post or comment, the site does not refresh after the first F5, only after the second F5. I wonder if the site shows up2date content for new visitors.
