Hi Joshua,
We had moved the large site scanner feature to the Professional release almost ten years ago – all the way back in November 2014.
Since you had a subscription to Akeeba Backup Professional in the past, you had downloaded and installed the Professional version which indeed had this feature. Since your subscription expired in 2022 you have now installed the Core version which does not have this feature.
You will need to re-subscribe and install Akeeba Backup Professional to get access to this feature.
