WordPress 3.0 is finally released with some great new features.
I just upgraded my site to 3.0 today. The upgrade was smooth, however, I find that export doesn’t work any more. When I try to push export button to download posts xml file locally, I get following error.

WordPress FAQ suggests checking spaces in wp-config.php and remove blank spaces before <?php tag or after ?> tag, I try and it does not help.
After trying deactivate on every single plug-in, I figure out it’s the plug-in Simple Tags that breaks WordPress 3.0 new export feature. Before Simple Tags owner releasing a fix, you can temp workaround this issue by deactivating Simple Tags plugin. After that, you will be able to get exported xml file to save.
hi Emma, i have the very same problem, however, even after i deactivated the Simple Tags, i still can’t not perform the export. Moreover, I got the following error when I tried to uninstall the plug-in. Any thoughts would be much appreciated.

Have you checked out this FAQ in wordpress site.

Thanks! It worked for me.
Thanks! Worked for me too.
Hi,
I’m facing the problem with Wp 3.0. Even after deactivating all my plugins, I now see NO error, but instead I see only the “Start date, end date, categories and Authors” options, but there is NO “Download File” option. Any suggestions Emma? 🙁
@carrie, sorry I don’t know. Mightbe post your question to wordpress forum?
