Hello,
When I updated to php 7.1.15, I have got these error lines on each page with Office Template:
Warning: A non-numeric value encountered in ~/public_html/plugins/system/officehelix3/core/officehelix3.php on line 472
Warning: A non-numeric value encountered in ~/public_html/plugins/system/officehelix3/core/officehelix3.php on line 472

Code on line 472 in officehelix3.php file:
$column->className = 'col-sm-' . (self::getColXsNo($column->className) + $last_col) . ' col-md-' . (self::getColXsNo($column->className) + $last_col);
Do you have the right code, it seems this is a compatibility trouble with php 7.1.x version?
