ISPConfig 3 (nginx) + VBSEO for Vbulletin forum

Dear all,

Anyone successful setup vbulletin 4.x using VBSEO 3.6.x under ISPConfig 3 (nginx base)?

I try all the rewrite rules (both insert into nginx Directives@ISPConfig 3 panel and edit directly to the vhost file as well) but all result as 503 or 403 errors
(without VBSEO is OK)

Below is my base rewrite rules insert into vhost (the /forums/ just as a sample in my case changed to / only)

Code:

location /forums/ {
rewrite ^/forums/((urllist|sitemap_).*\.(xml|txt)(\.gz)?)$ /forums/vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 last;

try_files $uri $uri/ /forums/vbseo.php?$args;
}

location ~ /forums/(.*\.php)$ {
rewrite ^/forums/(.*)$ /forums/vbseo.php last;
}
location /forums/vbseo/(includes|resources/html|resources/xml)/ {
	allow      127.0.0.1;
	deny      all;
}

Pls share your result if any DONE it properly!

Many Thanks and Best Regards
