WordPress MU

My apache2 error log is growing huge with these 2:

WordPress database error Table 'hubbledata.wp_addingblocks' doesn't exist for query SELECT * FROM wp_addingblocks WHERE enabled='1' made by require, require_once, include, get_header, locate_template, load_template, require_once, wp_head, do_action, call_user_func_array, addingblocks_css

WordPress database error Table 'hubbledata.wp_addingblocks' doesn't exist for query SELECT * FROM wp_addingblocks WHERE enabled='1' made by require, require_once, include, get_footer, locate_template, load_template, require_once, do_action, call_user_func_array, addingblocks_html

Apparently this dosen't visibly affects my site, but apache2 records this error to every ip.
What I understand from this error is that I need wp_addingblocks table.
Can you help me please?

This isn't a default table in WordPress or WordPress MU.

you're in the MU forums, btw.

Look for a plugin called "adding blocks"

Yes andrea, a MU install is what my server runs :) I'm not here by accident. Thank you very much for the reply.
It turns out that the problem was exactly the "adding blocks". My friend forgot to tell me about this little plugin. Removed it and the error stopped showing in the log.

Well, I mention it because there was just the use of WordPress and not MU. :)

We get a lot of people wandering in here with single-wp questions. :)
