By default the event history log is kept for 30 days (60 days on sites that installed Simple History before version 5.25.0). This can be changed using our Premium add-on.
This is to prevent the log from growing to large, which can be a problem if your website is hosted on a low end web hosting solution.
If you want to modify the number of days to keep the log, the easiest way is to use our Premium Add-on to set the number of days using a GUI.

Using a filter
This solution is a bit more advanced. If you have access to your functions.php you can use the filtersimple_history/db_purge_days_intervalto modify the number of days. See example below.
Example: Use a filter to expand the log to keep 90 days in the log. Add this snippet to for example your functions.php-file:
add_filter(
"simple_history/db_purge_days_interval",
function( $days ) {
$days = 90;
return $days;
}
