I don't know if I make something wrong but using shortcodes give me errors. As far as I know after having firstly defined a reference like [acp author="..." title="..." id="author1" /] I should be able to use [acp id="author1"] for the next reference, right? This results in a broken reference for me.
I am usinge WP 3.4.2 with PHP 5.3 an I got an error msg aswell:
“Warning: Parameter 2 to array_multisort() expected to be a reference, value given in ../wp-content/plugins/academicpress/Acp/Utils/Spl.php on line 25″
unfortunately I don't have a clue
