POS Blank Page Resolved

Just to be clear : I’m not in the team.
I’m just a customer who wants find it by myself.

I’ve you have a blank page, go in your POS plugin directory.
Directory : include
File : class-wc-pos-template.php

Replace the 2 functions format_css, Format_js (for me line #195)
by this (The changes are in Bold)

/**
* Makes sure css is in the right format for template
*
* @param $style
* @return string
*/
private function format_css( $style ) {
if ( substr( $style, 0, 5 ) === ‘<link’ )
return $style;

if ( substr( $style, 0, 4 ) === ‘http’ )
return ‘<link rel=”stylesheet” href=”‘ . $style . ‘” type=”text/css” />’;
if ( substr( $style, 0, 11 ) === ‘/wp-content’ )
return ‘<link rel=”stylesheet” href=”‘ . $style . ‘” type=”text/css” />’;

return ‘<style>’ . $style . ‘</style>’;
}

/**
* Makes sure javascript is in the right format for template
*
* @param $script
* @return string
*/
private function format_js( $script ) {
if ( substr( $script, 0, 7 ) === ‘<script’ )
return $script;

if ( substr( $script, 0, 4 ) === ‘http’ )
return ‘<script src=”‘ . $script . ‘”></script>’;
if ( substr( $script, 0, 11 ) === ‘/wp-content’ )
return ‘<script src=”‘ . $script . ‘”></script>’;

return ‘<script>’ . $script . ‘</script>’;
}
