Hi, I have upgrade XenForo to 1.4.10 with : XenForo Updater After this it's okay but 1-2 minutes after this update : Account Suspended 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. Kind Regards, Yoann.M 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.
