I am having the same / similar issue. The entire site goes down. Here is the error:
Uncaught Error: Access to undeclared static property: wp_slimstat::$options in ../wp-content/plugins/wp-slimstat-user-overview/index.php:39
Stack trace:
#0 ../wp-includes/class-wp-hook.php(286): wp_slimstat_user_overview::update_checker('')
#1 ../wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(NULL, Array)
#2 ../wp-includes/plugin.php(453): WP_Hook->do_action(Array)
#3 ../wp-settings.php(471): do_action('wp_loaded')
#4 ../wp-config.php(52): require_once('/srv/users/serv...')

#6 ../wp-admin/admin.php(31): require_once('/srv/users/serv...')
#7 ../wp-content/plugins/wp-slimstat-user-overview/index.php on line 39
I have disabled it for now whilst I find out from the author how to fix it.
Cheers.
Hi,
It looks like you are using a quite old version of one of our premium add-ons. Please contact us at support.wp-slimstat.com with your license key to get a download link for the latest version.
