In function current() in file class-piklist-add-on.php is show this error:
Notice: Undefined index: file in X:\myAnyPath\wp-content\plugins\piklist\includes\class-piklist-add-on.php on line 212
Because in my Windows the path has backslash, and Linux just slash, I solved it adding the code:
$trace['file'] = str_replace('\\', '/', $trace['file']);
Guys, why you dont have this project in GitHub? How i can contribute?
