After 2.5 no visits registering in 'Visits Over Time' widget

After upgrading to 2.5 there is no data recording in the ‘Visits Over Time’ widget. The ‘Visitors in Real Time’ below it is capturing all visits, its just not recording in the VOT widget.
Any help much appreciated.

please setup the cron archiving as explained in: How to Set up Auto-Archiving of Your Reports - Analytics Platform - Matomo

Thank you for your reply. I have set up a cron job but, as a newby I’m confused with the end partof the cron script:

/usr/local/bin/php -f /home/yenco/public_html/piwik/console core:archive > /home/example/piwik-archive-output.log

The /home/example/piwik-archive-output.log points to where.
I have looked for a simular file in the piwik installation file but there’s nothing there that resembles ‘piwik-archive-output.log’

Many thanks
Hopefully not a newby for long


So sorry seem to have sorted it. Not sure if its because I selected:

‘Allow Piwik archiving to trigger when reports are viewed from the browser’

or whether I selected the correct folder on the Piwik installation. (not a busy website!)
Anyway thanks for the previous help
