First off, thank you for this plugin. It's exceptionally valuable.
I am experiencing a glitch on at least one of the 40 or so sites I have it installed on. These tables in mySQL have 18 million and 23 thousand rows respectively. In the case of the former, that's taking up ver 4Gig of space. Seems excessive and I'm getting messages from host that I'm using too much space.
Can I safely empty those tables while WF is still running? Or what is the protocol to do so? Not a PHP wiz.
Many thanks!
