Nginx Plesk Fix For one domain and enable php 5 opcache

I recently moved from a dedi to vps and everything works great apart from one domain. This now only seems to working with the apache module. Before fastcgi and Nginx with settings below worked perfect. I need to find someone who can find out whats going on and fix it. I also have installed php 5.5 i need someone to enable opcache and set up and test the cache properly. ## Taken from http://www.linux-magazin.de/Ausgaben/2012/01/Magento-Hosting/(offset)/4 # gzip compression gzip on; gzip_min_length 1100; gzip_buffers 4 8k; gzip_proxied any; gzip_types text/plain text/css application/x-javascript text/javascript application/json; ############################################ ## uncomment next line to enable light API calls processing #rewrite ^/api/([a-z][0-9a-z_]+)/?$ /[login to view URL]$1 break; ############################################ ## rewrite API2 calls to [login to view URL] (by now it is REST only) rewrite ^/api/rest /[login to view URL] last; ############################################ ## TRACE and TRACK HTTP methods disabled to prevent XSS attacks if ($request_method ~ "^TRAC[EK]") { return 405; } ############################################ location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ { expires 30d; add_header Pragma public; add_header Cache-Control “public”; try_files $uri @fallback; } ############################################ ## always send 404 on missing files in these folders if ($uri !~ "^/(media|skin|js)/") { set $rewrite_to_index 1; } ########################################### ## Deny access to release notes to prevent disclosure of the installed Magento version if ($uri ~* "/[login to view URL]") { return 404; } # Don't rewrite if file exists if (-e $request_filename) { set $rewrite_to_index 0; } ############################################ ## rewrite everything else to [login to view URL] if ($rewrite_to_index = "1") { rewrite / /[login to view URL]; } ############################################ ## Prevent character encoding issues from server overrides ## If you still have problems, use the second line instead charset off; #charset utf-8; ############################################ ## Add default Expires header ## [login to view URL] expires 365d; ##Taken from [login to view URL] # Hide the system directories location ~ ^/(app|includes|lib|media/downloadable|pkginfo|report/[login to view URL]|var)/ { internal; } # Hide the hidden files location /. { return 404; }
