I made a mistake and deleted some files in my domain through file manager. Can you please restore file manager and/or tell me how to restore all of its contents back to default. Thanks
If you go to your cPanel, there is a feature called R1Soft Backup. You can click on this and open a backup interface where you can restore your account to a condition it was in beforehand. Select the most recent date that you had the website in the state that you want it to be in now, and restore.
Also, if you use the Legacy File Manager, you can use the Recycle Bin feature and undelete files that were previously deleted.
