If you have plug-in Simple Tags enabled, try deactivate it.
WordPress 3.0 Cannot Export
Just figured out. It’s the plug in Simple Tags breaks 3.0 new export.
Disable Simple Tags and now export is working.
I guess I will have to wait for a fix from plug in owner.
I got exact same issue. Export button on longer works after upgrading to 3.0
Can someone please help.
