00440: $LinkUrl and $LinkAlt not set in urlapprove.php
Description: In function LinkHTTP() the $LinkUrl and $LinkAlt are not set as it is done in function LinkIMap() in pmwiki.php. After adding them as follows it seems to work:
$FmtV['$LinkText'] = $txt; // BALU
$FmtV['$LinkUrl'] = PUE(str_replace('$1',$path,$IMap[$imap]));
$FmtV['$LinkAlt'] = str_replace(array('"',"'"),array('"','''),$title);
Since this was only a try and error task I am not sure if the modification is all that needs to be done and if I did it correctly.
