The problem appears to be caused by call_user_func_array behaving differently 
in PHP 5.3+. Namely, the callback's function signature is ignored when deciding 
whether to pass arguments by reference.

The "confirmEdit" hook expects the first parameter to be a reference, but since 
call_user_func_array ignores this, it gets a value instead.

I'm not sure how this can be fixed - either by passing the variable as a 
reference explicitly, or by not using call_user_func_array anymore.

I changed:

        function confirmEdit( &$editPage, $newtext, $section ) {

to 

        function confirmEdit( $editPage, $newtext, $section ) {

in ReCaptcha.php and it seems to have fixed it

I tried downloading the latest package today and this fix was not in there.  
Can someone at Google update the package?  The fix is so simple!

I found the same problem, I made the change suggested in Comment 2 and it fixed 
it. The package isn't still updated. As is said in Comment 3, can someone 
update the package, please? Thank you.

I had the same problem and comment 2 fixed it as well.
This is a high-priority bug because it makes the plugin unusable.
I just downloaded it, followed the basic setup instructions and it gave an 
exception.
Anyone not finding this solution would fail to set it up correctly...
