Also the problem may be in sql connection cause when all users try to connect to database than i cant access phpmyadmin

Sadly, you are still using Kloxo-MR 6.5. So, some feature and optimize not exists.

For your phpmyadmin, try move your sql file (it's must file with .sql file-extension) to /tmp and then from phpadmin try import with select 'Select from the web server upload directory /tmp/'.

can you tell me how can i update to latest version.
I've tried this tutorial www.servermom.org/install-kloxo-mr-centos-vps/1832/ but i got conflict error with some file on 6.5

thanks for fast reply

If still not data. Better change to Kloxo-MR 7.0 with follow https://github.com/mustafaramadhan/kloxo/blob/dev/how-to-install.txt for step A + B.1.2.

[R1nk0]

when i run yum install kloxomr7 -y
im getting a huge list of error i have added an text attachment cause i could not post the code.

[MRatWork]

If you install Kloxo-MR 7.0 but your server already exists Kloxo-MR 6.5, run 'yum replace kloxomr --replace-with=kloxomr7; sh /script/upcp -y'.

i have updated im on version 7 now but all my domains are down i cant access any of them.
ftp works good  but domains cant be reached.

Login to your panel. You need update php setting in server, admin and client. Also update 'switch programs' and 'webserver configure'.

[MRatWork]

For 'switch programs', choose 'none' for all and then update. After that, choose 'nginxproxy' or 'hiawathaproxy' for web, 'none' for webcache, 'nsd' for 'dns' and 'bogofilter' for 'spam'.

Also change to 'simplicity' in 'appearance'.

after i did all that i run sh /script/restart-all and this is the error

For php-fpm issue, reboot or 'pkill -9 php-fpm; sh /script/restart-web -y'.
