Warning archive_main / Warning archive_errors

Hello,
I have Matomo installed through Wordpress. I encounter an issue.
This morning, I got the message “there is no data for this report” when I filtered the data of the day, and it seemed Matomo was not recording data since yesterday 16h.
But, after trying to understand the issue, Matomo was spontaneously fixed and even the data after 16h yesterday reappeared.

See below the system report, there is some warnings. Are they linked to the problem I encounter ? Are they “serious” ? I do not not how to fix them (especially the Warning archive_main).
