Publish or Update button is inactive

This thread was marked resolved but wasn't resolved.

I'm having the same problem 

Top of page error says: Please select one or more categories. I have selected categories. Still says that.

UPDATE button is inactive / grayed out.

If I uncheck “enable future action” in the PublishPress Future box, the update button becomes active again. But of course, then I can’t use the plugin.

I’ve tried rolling back the plugin (this has been an issue for a few months). That doesn’t help. I unchecked “Enabled for all new posts” in settings. That doesn’t help.


WP plugin version 3.3.1

Help?
