Reply To: The field "Show search in custom post types selectors" is not saving

I solved the issue,
there was a simple quote missing on the following line in the file:

settings/class/customposttypeseditable.class.php

line: 37

<input type='hidden' value=" . $this->data . " name='" . $this->name . "'>";

should be

<input type='hidden' value='" . $this->data . "' name='" . $this->name . "'>";
