I'm using WordPress 3.5.1 and I just installed CubePoints. I didn't have any error not until I activated the "Donate" module. I got this error above my pages
Warning: _() expects exactly 1 parameter, 2 given in /home/myhost/public_html/wp-content/plugins/cubepoints/modules/donate/donate.php on line 165
And when I try clicking on the "Donate" button on my CubePoints widget to search for a user, it can't find the user and will just output multiple radio buttons labeled as "undefined".
I'm afraid that CubePoints 3.2.1 is not fully compatible with WordPress 3.5.1
