Solved reinstalling a new version of WP branded by my provider that allows wp-cron or that correct something with the clock of the server??? Who Knows! The Time seems not right for my local area (it is UTC+0 nstead of +2) however… All seem to work now! TNX for this plug-in!!
I’m using only “WP Missed Schedule” but I had already try to deactivate this plug-in and work only with PE. No luck!
