Warning Message

This morning this warning was blasted on my dashboard (in several places):

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘GA_Admin::add_config_page’ was given in /home/content/w/e/b/myidname/html/my-blogname/wp-includes/plugin.php on line 339

and I’m wondering what to do about it. Any ideas? I did mess around a bit with a new plug-in, adding a line of code to (for FeedBurner) to acknowledge my site if someone else uses copy from it. That’s probably it, but not necessarily. I’m asking for ideas from the intelligent community before I go at it. I’m just a hack.

Thanks as always. I’m awesomely impressed at how this community gives help and support.
