Hello! I have completed a LibreNMS server migration, and everything works fine on the new server except for: the Alerts History page only shows “No results found!”. I can see active alerts on the Notifications page, but they never show up on the Alerts History page.
When I inspect the Alerts History page in the browser, I can see an error “ajax_table.php 500 (Internal Server Error)” (see attached):
Everything else looks fine on this server. Only the Alerts History page is malfunctioning.
This is the output of ./validate.php on this server:
