I am not a 100% sure if this is the same problem but…
The dynamic button isn’t showing up in my posts (There is a div with a link, but its display:none;)
If I set the button-type to static button everything works fine. I suspect, that the plugin’s js is not imported into the theme. But up to now I had no time to confirm this.

I’ve got the same problem. Unchecking the “Disable Flattr for this Post” box has no effect and is still marked after updating the page.
It seems as if the entry _flattr_post_hidden (1) & _flattr_btn_disabled (1) are not removed from wp_postmeta. After manually removing then from the db, the button is “unchecked” and the flattr-button is visible in the post.
Cheers!
