error in main.php
In other posts I read one mistake in the file main.php
// 401 file referenced since user should be logged in to view this page
the sentence include '401.php'; appear as a comment. So I deleted the two diagonals. But when I uploaded to my server, appear's nothing in this page(main.php) like some type of error. Then, I deleted the sentence include'401.php', and it works with out problem, but I can see this page without login, It`s because whe call 401.php, but does not work with this sentence.
someone knows why?
