If you've modified your report page footer and you want to revert to the standard footer, go to Customisation > Footers and click on the Reset button at the bottom right of the Report footers page.

This will restore the standard Genovo page footer of your company name on the left and the page number on the right.

If your customised report page footer was implemented by Genovo (because your plan type doesn't provide the feature as standard), you'll need to request for it to be reset for you by submitting a support ticket.
