@fyoo can you give me a step by step on what you did?
I am trying to make this work.
I cannot find anything like wp_cf7dbplugin_submits.
I have found the related blog's tables but there's noting.
I want to get to work on one blog on my multi site (BTW: I worked a few months ago but reading about it here it looks like an accident for it to have worked).
Did you add it to the mu-plugins dir or uploaded as a normal plugin.
And did you activated it on the individual blog?
And what did you do at phpmyadmin?
Thanks
Johan
