Hi all, just a heads up.
I'm developing a theme, and this project requires the use of the share-this plugin. Most end-users will never see this error message, but on line 606 of sharethis.php there is a call to add_options_page() which uses 'manage_options' as a constant (missing quotes). Easy fix, just wrap manage_options in quotes to get rid of this warning.
Could you add this bit of polish to the next release please?
Thanks,
Greg J!
