Beware: Blocks login
by martinpelletier·4 months ago·1 reply
Blocks login even if login protection is not checked in dashboard. Moreover, the right answer does not allow to login. You get locked out your own WP site.
Just perfect!

I’m using this plugin for 1-2 years and it’s the best solution yet.

Frequently Asked Questions
Changelog
2.6.13
- Fix [Admin UI]: Resolved sidebar/navigation not rendering on sites with WooCommerce or other React-based plugins. The plugin now uses WordPress’ built-in React instead of bundling its own copy, preventing duplicate React instance conflicts that broke context providers.
- Fix [Cron]: “Daily Telemetry” cron job no longer runs when telemetry is disabled. Previously, disabling telemetry in the admin UI only took effect on the next page load; the cron could still fire in between. Cron state is now synced immediately when settings are saved.
- Fix [Cron]: Audit log no longer shows “Daily Telemetry completed” entries when telemetry is disabled. The audit hook for the telemetry cron is now only registered when telemetry is active.
