After installing Massive dynamic, based on your server configuration you might face this error:
Parse Error: syntax error, unexpected T_FUNCTION in /home....../wpalchemy/MetaBox.php on line 547
It seems like a huge problem, but the solution is very easy.
You are getting this error, because your server is running an outdated PHP version. To resolve this issue, you have to run this theme on a server with PHP version 5.4 or above. So please contact your server administrator and ask them to update the PHP to 5.4 or above.
