After we switch on your plugin, it uses 200% of our server database, when we switch it of it calms down, but we are sure that its your plu=ging which cause this problem. Please could you check and help us fix this issue? There you have screen shot of serever CPU usage and its growing all the time. there is like nonstop qeuery.
There is a possibility this issue occurred on your server with some settings, nobody else reported it yet. It can only be fixed if it can be reproduced.
I have released a new version, in which you will see a table under the crons tab. I doubt, somewhere cron job scripts maybe being triggered without your consent or you set it with the wrong values. Because only cron job scripts wrong values can engage the database crazily, nothing else. Anyways, with the latest improvement, you will be able to allow/reject the cron request after verification if it is your hosting server IP or an anonymous request is trying to engage you.
