The new version of the terms-of-service plugin is not working properly

The new version of the terms-of-service plugin is not working correctly:

1. The new html-editor is not preserving the formatting
2. On the site-activation page, the following error is displayed just above where it reads "Your account is now active":

string(25) "CLEAR TABLE: bcn_84_terms"

This error still appears even though I have the following code in my wp-config file:

ini_set( 'display_errors', 'off' );

Is it possible to reload the previous version on your system until the upgraded version can be fixed?

And is there now any action which I need to take for site 84 in terms of the above error?
