Manual install did not work. Also got the same error when trying to install Tweet! for WordPress
Hi. I am getting the same error. I used the auto-install feature and when I tried to go into the settings (assuming that is where I will need to enter my Twitter info), I received the same error. I tried uninstalling completely (removing all files as well) and reinstalling the plugin and it still didn’t work. Please advise if you have any suggestions, as this sounds like a great plugin. I am going to try a manual install.
