I'm running a multiple blogs setup under one domain. I'm the administrator of my site, and in addition I have one lesser user account for managing blogs other than the site root. I've installed the Flattr plugin, but I've only been able to make it fully work on the first blog I activated it in (under my non-admin account). In others, the "Connect" link on the plugin's options page does nothing: it seemingly just reloads the options page. That is, the connection is never made (it just says "None").
I tried disabling the plugin in the blog it does work in, but that didn't help. I also tried different combinations of disabling/enabling the plugin in different blogs, using my administrator account, but it didn't make a difference either. I also tried the Network activate option, to no avail. So I'm starting to suspect there's some kind of a flaw in the plugin's support for multiple blogs.
So, how can I connect my Flattr id to the rest of my blogs?
