and the post visits don’t respond to reality…
Can you see if Slimstat is reporting an error under Settings > Maintenance > Debugging?

Could you send us a screenshot at http://support.wp-slimstat.com ?
ok, I have your plugin on tons of my sites. I just checked, and this seems to be the only installation that has this error.
what do you suggest?
ok, I have a new plugin (6 days old) all-in-one-schemaorg-rich-snippets
I am going to disable it, and we’ll see if that is the problem, ok?
Is the MaxMind database installed? (Settings > Maintenance)
yes, the Maxmind database is installed.
disabling the snippets plugin didn’t solve the problem
I can move all the plugins out of the plugins folder temporarily, to see if it is an incompatibility.
many plugins are updating now, and they may have made incompatible updates…
Is the server configuration the same on all the sites? (version of PHP, operating system, etc). Maybe your MaxMind DB is corrupted on that site? Can you uninstall the db (NOT SLIMSTAT!) and install it again using the corresponding button under Settings > Maintenance?
