It is no longer possible to delete the log starting with version 4.6.0. You can only do it manually from the database, but this implies certain possibly unwanted results.
There are 3 tables that take into account the reports and the number of downloads:
- download_log: used for more detailed analysis + the tables in the reports with the top downloads and user downloads
- dlm_reports_log : used for the chart
- dlm_downloads: used for calculating download count in front, All Downloads and Dashboard widget
Deleting the dlm_downloads table will affect the front, dashboard and general download counts. The other 2 tables are the ones that are required to process the Reports page.
We recommend that you do a back-up of your site before you delete anything.
