If it’s asking you for FTP login information when you try to update wordpress or a plugin, you don’t need to do that! Chances are you don’t have permissions correctly configured on that directory. Make sure apache owns the directory. On ubuntu, this will probably work (depending on which user owns apache):
Mysql-client 5.6 doesn’t seem to exist, and you don’t need it. Phpmyadmin installs mysql-client 5.5 automatically, and that works with mysql server 5.6. If you’re having issues, you probably need to run sudo dpkg-reconfigure phpmyadmin.
SET @@global.sql_mode= "; will set it temporarily. (to see if it will fix your problem)
To turn it off permanently, add this setting to your my.cnf (probably in /etc/mysql/my.cnf if you’re using ubuntu):
[mysqld]sql-mode=
If you’re having issues getting this setting to work in your my.cnf, look for another my.cnf in /opt/mysql/server-5.6/my.cnf or elsewhere on your system using the find / -name 'my.cnf' command.
This script needs to go into your WHMCS hooks folder (root/includes/hooks/):
<?phpfunctionsend_invitation_email($vars){$command="sendemail";$adminuser="admin";// Your admin username$values["messagename"]="Google Groups Invitation";// exact name of e-mail template$values["id"]=$vars['userid'];$results=localAPI($command,$values,$adminuser);}add_hook("ClientAdd",1,"send_invitation_email");?>
