Uncaught DivisionByZeroError

Hi,

Since today I receive the stack trace error Uncaught DivisionByZeroError. It doesn’t open the frontend form.

To my knowledge it means something is being divided by zero. The error is coming from here:

\WH_GF_Multicolumn_Public_Form_Current.php on line 170

I see there’s a formula dividing columns widths:

$columnWidth = is_numeric( ( 100 - $columnWidthCount ) / $this->rowColumnArray[ $this->rowCounter ] ) ? floor( ( 100 - $columnWidthCount ) / $this->rowColumnArray[ $this->rowCounter ] ) : 1;

Might this conflict involve theme settings? Any idea where to look at and what is being done here?

With thanks,
Demian
