Hi, after searching a lot in the net, I've could not find any answer to my problem. I'm using nginx in debian and in the error log I'm getting the following error message:
FastCGI sent in stderr: "PHP message: PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'register_shortcodes' not found or invalid function name in /wp-includes/plugin.php on line 406" while reading response header from upstream, client: *, server: xxxxxxxx, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "xxxxxxxxxxxx"
I have some shortcodes in my function.php:
add_action( 'init', 'register_shortcodes');
Could you please tell me what is happening?
