Thanks, I'll check my stylesheet, I don't want to ignore PHP warnings.
Your code reads
// file: "./packages/phpdocx/Classes/Phpdocx/Transform/HTML2WordML.php"
// line: 2198
if (isset($properties['border_' . $value . '_style'])
&& $properties['border_' . $value . '_color'] != 'none'
&& $properties['border_' . $value . '_width'] != null)
It would be safe to add a `isset($properties['border_' . $value . '_width']) ` to get rid of that warning. Additionally, there should be a default width set anyway by the Docx creator.
// file: "./packages/phpdocx/Classes/Phpdocx/Transform/HTML2WordML.php"
// line: 2198
if (isset($properties['border_' . $value . '_style'])
&& isset($properties['border_' . $value . '_color'])
&& isset($properties['border_' . $value . '_width'])
&& $properties['border_' . $value . '_color'] != 'none'
&& $properties['border_' . $value . '_width'] != null)
