SymptomsThe following error is shown in Parallels Plesk Sitebuilder when opening a site in Wizard:
Message: Table 'site_page' - SQLSTATE[08S01]: Communication link failure: 1153 Got a packet bigger than 'max_allowed_packet' bytes
CauseThe length of the Sitebuilder request exceeds the MySQL limit max_allowed_packet. The limit is set to 1M by default.
ResolutionIncrease the max_allowed_packet value in /etc/my.cnf and restart MySQL service. For example, to increase the limit to 16M, do the following:
~# /etc/init.d/mysqld restart
