Tried to access webmail and presented with this error

Hmmm. Still using ruid2.

Because already using nginx but php-type still ruid2, try change to 'apache' on 'switch applications' and 'php-fpm_event' on 'webserver config'. And then, if you want, change back to nginx.

Thanks for your reply
I have changed to apache and php-fpm_event and it worked fine
but when cgain I changed back to nginx same error

Yes, I am wrong. Forgot something for nginx config.

Thanks Mustafa
It worked now
What you think could we use Kloxo-MR on production server

MRatWork · « **Reply #8 on:** 2013-08-14, 02:36:14 »

I have many servers as production servers (certain as share-hostings) using Kloxo-MR (using Kloxo official before). So, it's your choice.

It's ok for private servers but need better knowledge for share-hosting.

If using nginx or lighttpd or hiawatha (exist in 6.5.1) alone (that mean not their proxy), try switch to apache first and then change php-type to php-fpm_worker/_event. After that, you can change back to nginx.

It's because Kloxo-MR confuse about related to php. You see in sysinfo, Kloxo-MR not inform your php version.

That it.

befree22 · « **Reply #11 on:** 2014-03-11, 20:57:15 »

It worked after applying your fix ==> Switch Program to apache first and then change php-type to php-fpm_worker/_event in Webserver Config. After that, you can change back to nginx.

I did have to reinstall Nginx though.

Thanks

befree22 · « **Reply #12 on:** 2014-03-12, 14:45:08 »

Yesterday, I tried logging into Kloxo-MR panel but I have no access -- "unable to connect to server" error.

It seems like httpd was uninstalled and isn't working now. I never uninstalled httpd. Could you help me figure out why httpd was removed and fix Kloxo-MR login access?

MRatWork · « **Reply #13 on:** 2014-03-12, 14:50:29 »

Hi,

Kloxo-MR not using httpd (aka apache) for their panel but hiawatha.

If you find "unable to connect to server" look like something wrong with mysql. Try 'sh /script/restart'.

xamer · « **Reply #14 on:** 2015-01-16, 09:58:24 »

I've got the same problem 502 error on nginx server.

I update Kloxo 6.5 to KloxoMR7 and that problem appears. i was trying to fix ==> "Switch Program to apache first and then change php-type to php-fpm_worker/_event in Webserver Config". After that, I changed back to nginx and 502 error stays.
Also i used:
sh /script/fixweb
sh /script/fix-chownchmod

and finally helped
sh /script/fixweb-all
