it doesn't work on multisite

Hi,

I installed this plugin on WP using multisite.
On the main site, it works. But on the 2nd site, it doesn’t.

If I turned on the “SQL Debug” in [Dashboard]->[Slimstat]->[Settings]->[Maintenance], this message was printed.

[08-04-16 04:03 pm] 215 Error: Table ‘wordpressdb.wp_2_slim_stats’ doesn’t exist

More informations are as follows.
