When I use WP Flash uploader to add images to my posts, I get the following error:
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'Tweetbacks_Admin::add_config_page' was given in /blog/wp-includes/plugin.php on line 339
I receive this message instead of the normal interface that allows me to position and adjust my image.
Any ideas on how to fix this? Tweetbacks is working on my site, but out of nowhere I get this error.
