hi! Thanks for this great plugin.
I am using WP Multisite, and although the plugin works perfect on the main site, am having this problem on subsites (=subdomain blogs): I am not able to Add Title (even if I write the name of the new title, it is not saved).
I deactivated all the other plugins, so I guess it is not a problem of incompatibility.
Maybe it's related to WP Multisite?
