Yes this is the problem, but is only when the XOOPS_URL have subdirectory... in my case /sito.
This problem i had in the past is resolved, in other file.
Now only in viewpost.php, if i modify the line $nav->url = XOOPS_URL . $nav->url; the problem is resolved,but i think is not the solution because $nav->url = XOOPS_URL . $nav->url; is present in other file without problem.
