First of all, this is great plugin, thank you!
The plugin processes the donation fine on WordPress 2.8.5., and the donor is taken to the "Thank You" page afterwards.
But none of the donation details are entered into the database or displayed. I.e. the donor wall is not updated at all, nor the total donations page. The donor is also not sent a thank you email. The donor's details are furthermore not entered into the database or displayed in the backend.
I tried the fix posted by the author here, but that merge did not work.
Any chance you could please update this plugin to address those issues? :)
