I have upgrade XenForo to 1.4.10 with :
After this it's okay but 1-2 minutes after this update :
Appears on my website for this reason :
“Thousands of email in a few minutes
This hosting package is currently suspended.
You cannot continue to use or manage this package until it is reactivated.”
Just after update.
Small information when I did the update with "XenForo Updater" initially I got this error: An exception occurred: Mysqli prepare error: MySQL server has gone away in /home/phoenix/public_html/library/Zend/Db/Statement/Mysqli.php on line 77
I use the back on the browser button and I restart and it it is done properly then.
Thanks for your responses and help.
Edit (more information by my hoster):
Thats all genre forum notifications new message, new response.
I understand your concerns, but unfortunately many thousands of messages in minutes represents a security risk for our IP and the server load.
P.S.: Excuse me for my bad english, I'm French.
