Errors on Google import using Admin page

it’s actually getting worse, I got the following messages:
Matomo cannot find PHP shell_exec, exec, nohup.
I have those disabled/deleted because I followed other suggestions. So it’s really not clear how to setup Google Importer.

Plus, this other error:
The last archive was successfully executed 3 days ago. Check to have configured a crontab to call core:archive and have configured MAILTO. You can try with command: /.../console --matomo-domain=/..../ core:archive
But the tutorial for that says that it’s not needed with Wordpress.

No clue really.
