after i have finished installed phpdig1.8.8 ,it show me the follow error message!

"Table dbprefixengine missing. Table dbprefixexcludes missing. Table dbprefixkeywords missing. Table dbprefixsites missing. Table dbprefixspider missing. Table dbprefixtempspider missing. Table dbprefixlogs missing. Table dbprefixclicks missing. Table dbprefixsite_page missing. Table dbprefixincludes missing. "

Your connect.php file is misconfigured. Set PHPDIG_DB_PREFIX to the correct value.
