Hello there @riversatile !
Thank you for bringing this into our attention!
Can you please let me know if you are using the latest WP Activity Log plugin across the MainWP network (5.6.1)? If not, I would suggest that you update everything first, then try again.
Also, please share with me the WP Core and PHP version that this site runs, and if there are any specific steps to trigger these warnings by any chance; the more details you can share, the better!
Looking forward to your update!
Hi,
Yes, version 5.6.1 is active on the server and on all child sites.
WordPress core version: 6.9.4
PHP version: 8.3.30
Apparently, the Warning occur when I click “Retrieve Activity Logs Now” from the Activity Logs panel (/wp-admin/admin.php?page=Extensions-Wp-Security-Audit-Log).
I think this is is also the case when MainWP server Cron tasks runs.

Thank you for the details provided @riversatile !
I’ve added an internal ticket about this and we’ll surely tackle this in a future plugin update, so stay tuned. I cannot offer any ETA just yet, but we’ll definitely look into.
I do appreciate your patience and also for bringing this to our attention!
Hey there @riversatile !
We have just released version 5.6.2 a few moments ago which should fix these. Can you update and let us know how it goes?
Many thanks!
