parse error message and my si doesnt load

Hi there,
I tried to install WP-Paginate plugin, adding the code

if ( function_exists( ‘wp_paginate’ ) ) {
wp_paginate();
}
else {

in functions.php file (I use twentyeleven theme), but now, anytime I want to enter my site it doesnt load, but the following error message shows up:

Parse error: syntax error, unexpected T_ENDIF in /data/web/virtuals/47208/virtual/www/wp-content/themes/twentyeleven/functions.php on line 464

I even cant enter to the functions.php again to undo what I did before. My page is: http://bonapetitprague.com/

Please, advise what to do.
