Hopefully, I got this right not any more of that non-numeric value error. Thanks for that, what I read was to change this in categories_ul_generator.php
line #53:
PHP Code:
$result = sprintf($this->parent_group_start_string, ($submenu==true) ? ' class="level'. ($level+1) . '"' : '' );
to the following:
PHP Code:
$result = sprintf($this->parent_group_start_string, ($submenu==true) ? ' class="level'. ((float)$level+1) . '"' : '' );
also line 73:
PHP Code:
$result .= $this->buildBranch($category_id, $level+1, $submenu, $category_link . '_');
to the following:
PHP Code:
$result = sprintf($this->parent_group_start_string, ($submenu==true) ? ' class="level'. ((float)$level+1) . '"' : '' );
