Archiving has not yet run successfully - Wordpress plugin error

We recently updated our website theme and hosting provider and Matomo is no longer archiving data to our dashboard. Visits are being logged in real time, but not saved anywhere to view past data. In my diagnostics report the only item showing up as an error says:

Last Successful Archiving Completion error Archiving has not yet run successfully

It’s unclear to me why the archiving is failing. Any suggestions for what to try?

i encountered a similar problem, only with the additional diagnostig, that matomo doesnt find the php cli, so im not sure if it aplies 100%, but i found a temporary work-around by archiving data manually via the troubleshooting tool.

this doesnt solve the underlying problem, but at least u get to see data in ur reports
