[Plugin: AJAX Archive for WP Themes] broken

Hi there, I’m unable to activate the plugin – WordPress 3.4.1 returns this error:

Parse error: syntax error, unexpected T_ENDFOREACH, expecting T_FUNCTION in \wp-content\plugins\archive-ajax\archive-ajax.php on line 161

Anyone able to help here?
I’m using the Constellation HTML 5 base theme
