I have been working with custom posts and custom taxonomies, and i figured that your plugin could fit on my project turning it more complex and usefull.
So I tried to install Query Multiple Taxonomies plugin but i can't activate it, it shows the following error:
Fatal error: Call-time pass-by-reference has been removed in C:\xampp\htdocs\wordpress\wp-content\plugins\query-multiple-taxonomies\core.php on line 236
My php version is PHP Version 5.4.4 and i'm working on localhost as you see.
My knowledge about php is very poor.
I would appreciate a help.
thank you very much,
