General ERROR SQL ERROR [ mysqli ]

[creativx]

Hi, trying to post a message on my board and i get this:

General Error
SQL ERROR [ mysqli ]

MySQL server has gone away [2006]

SQL

SELECT topic_type, forum_id FROM phpbb_topics WHERE topic_id = 0

BACKTRACE

FILE: includes/db/mysqli.php
LINE: 143
CALL: dbal->sql_error()

FILE: posting.php
LINE: 872
CALL: dbal_mysqli->sql_query()

Haven't even touched anything delicate...so it's unlikely to be something i've done...phpbb boards say this is a hosts end problem, any ideas?

thanks

pleaase? no suggestions on how to fix this?...it's happening everytime i try to post a message on board...
