VCF file comes out empty by default

I’m running your plugin and would only get empty VCF files. Looking at the Apache error log, I could see an error:

[Sun Mar 12 21:58:08.539576 2017] [:error] [pid 629] [client x.x.x.x:58684] PHP Warning: Invalid argument supplied for foreach() in /.../wp-content/plugins/team-vcard-generator/includes/single-team_member.php on line 403

I looked at the code and it assumes that $dia[1] is an array.

I protected that foreach() loop with an if() so it would not fail there and the result is that I get the VCF files. I suppose, however, that the loop should work but maybe it was $dia[0] instead?

In any event, that is probably not the fix, but it gets me going.

if(is_array($dia[1])) 
{ 
                            $cuenta_horarios = count($dia[1]); 
                            foreach ($dia[1] as $numero => $hora) { 
                                if (($numero + 1) == $cuenta_horarios) { 
                                    $horas.="<span>" . $dia[1][$numero] . "-" . $dia[2][$numero] . "</span></td>"; 
                                } else { 
                                    $horas.="<span>" . $dia[1][$numero] . "-" . $dia[2][$numero] . "</span> "; 
                                } 
                            } 
}
