No WebGUI white blank page

  • Greetings all,


    I need help, have a problem with my WebGUI, its just a white blank page. I'm not sure what I did wrong with it.
    Connecting through ssh working fine, I'm not sure why, but I still can open transmissionbt from port 9091.
    I used to use omv admin page from port 8888, but it always give me blank page. Btw I'm using Chrome with Incognito mode.
    Tried on other computer with different browser not also not working. I've also read some posts related about this topics. i.e 502 Bad Gateway after 1.x -> 2.0.10 upgrade and some others.


    Reconfiguring WebGUI with omv-firstaid to port 8888 also not working. port 80 gives me "Welcome to nginx on Debian!" message


    But I got this error message when I change to port 80:


    Code
    Updating web administration settings. Please wait ...
    {"response":null,"error":{"code":4000,"message":"Failed to execute command 'export LANG=C; nginx -t 2>&1': nginx: [emerg] a duplicate default server for [::]:80 in \/etc\/nginx\/sites-enabled\/openmediavault-webgui:30\nnginx: configuration file \/etc\/nginx\/nginx.conf test failed","trace":"exception 'OMVException' with message 'Failed to execute command 'export LANG=C; nginx -t 2>&1': nginx: [emerg] a duplicate default server for [::]:80 in \/etc\/nginx\/sites-enabled\/openmediavault-webgui:30\nnginx: configuration file \/etc\/nginx\/nginx.conf test failed' in \/usr\/share\/openmediavault\/engined\/module\/webserver.inc:41\nStack trace:\n#0 \/usr\/share\/openmediavault\/engined\/rpc\/config.inc(180): OMVModuleNginxAbstract->applyConfig()\n#1 [internal function]: OMVRpcServiceConfig->applyChanges(Array, Array)\n#2 \/usr\/share\/php\/openmediavault\/rpcservice.inc(125): call_user_func_array(Array, Array)\n#3 \/usr\/share\/php\/openmediavault\/rpc.inc(79): OMVRpcServiceAbstract->callMethod('applyChanges', Array, Array)\n#4 \/usr\/sbin\/omv-engined(500): OMVRpc::exec('Config', 'applyChanges', Array, Array, 1)\n#5 {main}"}}

  • Here what i got for ls -la /etc/nginx/sites-enabled


    Code
    total 8
    drwxr-xr-x 2 root root 4096 Mar 30 20:47 .
    drwxr-xr-x 7 root root 4096 Mar 30 17:53 ..
    lrwxrwxrwx 1 root root 34 Mar 17 11:16 default -> /etc/nginx/sites-available/default
    lrwxrwxrwx 1 root root 48 Mar 30 20:47 openmediavault-webgui -> /etc/nginx/sites-available/openmediavault-webgui


    and theres no 2.2.3 update

  • The 2.2.3 update hasn't been released yet and wouldn't fix your issue.


    rm /etc/nginx/sites-enable/default
    service nginx restart

  • default file removed, nginx restared but still blank page.


    I also reconfigure WebGUI with omv-firstaid to port 80. The error messages i got before now gone.
    Tried to access it from port 80, still blank page

  • Did you clear your browser cache? Post the output of the following:


    wget http://localhost/
    head -n 5 index.html

  • head -n 5 index.html return no output

  • I tested wget http://localhost/ and head -n 5 index.html on running VM.


    Result:


    HTML
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml"><head>

    body {background-color: #ffffff; color: #000000;}
    body, td, th, h1, h2 {font-family: sans-serif;}


    What did I do wrong? Could i messed up my sites/available and sites/enable?


    Any suggestion to recover nginx configuration from VM?

  • Your site file is there. omv-mkconf nginx re-creates the config. No idea what you did. Try: apt-get install --reinstall openmediavault

  • Recreating the config with omv-mkconf nginx and apt-get install --reinstall openmediavault doesn't help.


    I tried 502 Bad Gateway after 1.x -> 2.0.10 upgrade


    Not sure why my /etc/nginx/fastcgi_params missing fastcgi_param SCRIPT_FILENAME $request_filename; line.
    By adding that line and service nginx restart now WebGUI working again.


    Thank a lot for the help and suggestions.

  • Maybe an nginx upgrade caused this. I think omv-mkconf should create/check the fastcgi_params. I will file a bug report.

  • If I recall it correctly I had a similar situation the other day and found that nginx was updated from the backports repo. So I had nginx version 1.6 instead of the "normal 1.2". I fixed it by downgrading to 1.2 (apt-get install nginx/wheezy nginx-full/wheezy).
    As you fixed your problem with changing the fastcgi config would you do me a favour and check your nginx version? Maybe I could have fixed my setup the same way ... ;-)
