Only now I realized I opened an issue on the wrong repository on GitHub. So I’m copying here the details.
I get the following error with Mad Mimi WP plugin version 1.5.1 and PHP 5.5:
PHP Parse error: syntax error, unexpected end of file in wp-content/plugins/mad-mimi/mad-mimi.php on line 621
I guess the problem is related with the new default value for short_open_tag in PHP. By replacing <? with <?php in line 176 the error is fixed.
I ran into this same problem, you guys really should fix it, it’s an easy fix!
