MySQL Error : Got a packet bigger than ‘max_allowed_packet’ bytes
Error Number : 1153
You or your host will need to increase the ‘max_allowed_packet’ in my.cnf, then restart MySQL. I recommend at least 32M for this setting.
In addition to the vB settings, the allowed size of the attachments depends on the PHP and MySQL configuration. You may need to check and changechange the upload size for both PHP and for MySQL.
Note, you’ll need to have root access to the server to do this (or have your host do it.) Make these changes to php.ini:
upload_max_filesize = xM
Change it to the size (‘x’) you want in Megabytes. Restart the webserver and MySQL after making these changes. I recommend at least x=32M for this setting.
