website down probaly because of bug in wp-testing

Hi there,
my website just crashed recently. The error logging says:

Fatal error: Uncaught exception ‘fSQLException’ with message ‘MySQL error (Table ‘dbz7oyse.wp_wfNet404s’ doesn’t exist in engine) in SHOW CREATE TABLE “wp_wfNet404s”‘ in /home/webextie5/html/apps/maennerpsych/wp-content/plugins/wp-testing/vendor/flourish/flourish/fDatabase.php:456 Stack trace: #0 /home/webextie5/html/apps/maennerpsych/wp-content/plugins/wp-testing/vendor/flourish/flourish/fDatabase.php(2565): fDatabase->checkForError(Object(fResult), NULL) #1 /home/webextie5/html/apps/maennerpsych/wp-content/plugins/wp-testing/vendor/flourish/flourish/fDatabase.php(3028): fDatabase->performQuery(‘SHOW CREATE TAB…’, Object(fResult), Array) #2 /home/webextie5/html/apps/maennerpsych/wp-content/plugins/wp-testing/vendor/flourish/flourish/fDatabase.php(2935): fDatabase->run(‘SHOW CREATE TAB…’, ‘fResult’) #3 /home/webextie5/html/apps/maennerpsych/wp-content/plugins/wp-testing/vendor/flourish/flourish/fSchema.php(1232): fDatabase->query(‘SHOW CREATE TAB…’, ‘wp_wfNet404s’) #4 /home/webextie5/html/apps/maennerpsych/wp-conten in /home/webextie5/html/apps/maennerpsych/wp-content/plugins/wp-testing/vendor/flourish/flourish/fDatabase.php on line 456

As the code refers to wp-testing, I thought you might be able to help me out to get my website running again.
Thanks for any assistence,
