I am facing problem in transferring phpBB forum to new server.

Getting the error in index page:

    SQL ERROR [ mysql4 ]
    Table 'abdrc_forum.phpbb_config' doesn't exist [1146]
    An sql error occurred while fetching this page. Please contact an administrator if this problem persists.

Code (markup):

I am trying to import the backup of the database using Bigdump and after 96% the database is imported I am getting the following error:

    Error at the line 3005: SET character_set_client = @saved_cs_client;
    Query: SET character_set_client = @saved_cs_client;
    MySQL: Variable 'character_set_client' can't be set to the value of 'NULL'

Please help me to solve this problem.

Thanks in advance,
