Forum After Upgrating to vb4 suite have a blank page problem
 

hello

after upgrade from 3.8.4 pl1 to publishing suite 4 pl1 i got a blank page error .

I checked all possible approaches from
http://www.vbulletin.com/docs/html/main/blank_pages

but all defined hints haven't been solved my problem .

today i seen this thread :
Mod Rewrite Friendly URLs => .htaccess

then i add below codes to .htaccess file in root forum directory and Mod Rewrite Friendly URLs enabled

Code:
# Author: Matty Asia
# Version 1.6
# Downloaded from: http://www.vbulletin.com/forum/showthread.php?325798

RewriteEngine On
Options +FollowSymLinks

### THIS IS A LITTLE EXTRA SECURITY AND CAN BE REMOVED

RewriteRule ^includes/(.*) index.php
RewriteRule ^vb/(.*) index.php
RewriteRule ^packages/(.*) index.php

### THIS IS THE ACTUAL REWRITE

RewriteRule ^threads/([0-9]+)(?:/?$|(?:-[^/]+))(?:/?$|(?:/page([0-9]+)?)) showthread.php?t=$1&page=$2&%{QUERY_STRING}
RewriteRule ^members/([0-9]+) member.php?u=$1&%{QUERY_STRING}
RewriteRule ^forums/([0-9]+)(?:/?$|(?:-[^/]+))(?:/?$|(?:/page([0-9]+)?)) forumdisplay.php?f=$1&page=$2&%{QUERY_STRING}
RewriteRule ^blogs/([0-9]+)(?:/?$|(?:-[^/]+))(?:/?$|(?:/page([0-9]+)?)) blog.php?u=$1&page=$2&%{QUERY_STRING}
RewriteRule ^entries/([0-9]+)(?:/?$|(?:-[^/]+))(?:/?$|(?:/page([0-9]+)?)) entry.php?b=$1&page=$2&%{QUERY_STRING}
RewriteRule ^list/([^/]*/)([0-9]+) list.php?r=$1$2&%{QUERY_STRING}
RewriteRule ^content/(.*) content.php?r=$1&%{QUERY_STRING}
RewriteRule ^widget/config/([0-9]+) widget.php?r=config/$1&%{QUERY_STRING}
Now my problem solved correctly and now i haven't any problem :o
would you please answer to me * is this a permitted solution ? can i sure to healthy of my forum ?
how can i change my forum to Standard URLs position without any problem ?

thanks
