Finally solved it! in case you’re wondering this is what I did.

$categorias = $bnf_exc_cat;
	if ($categorias){
		$categorias_exc= implode(",",$categorias);
	} else {
		$categorias_exc="";
	}

I assume this was because it was attempting to implode ‘nothing’.

Hey MichaelH, thanks for your quick reply.

I don’t know why I posted it with a period, I do have it with a comma.
It looks just like your example and the warning still shows up.
I’ve been trying to find what seems to be the problem and it looks like it shows up only when the options are empty. Every time I check a category it gets excluded with no problem from the header. But, as soon as I uncheck them the warning shows up.

How can I fix this?
