[Plugin: Statpress Visitors] StatPress Visitors on Shopperpress

Sorry to reply late but WordPress does not report to the developer that there is a new post!

This plugin works only on the $ _SERVER and therefore there is no reason to interfere in it anything to your sales site.
I suggest you still do not keep logs of all your visitors to the site online, delete after one month, but to make a copy on a site installed locally on your computer, your site will gain in speed.

Also avoid the use of widgets that slow page loading.
