Things are not quite right with your site. You have tried troubleshooting the issue for the last four hours and you are getting frustrated. Then you remember that you have been making daily backups of your site. The question is, "How do I restore my site from the backup?" This tutorial will take your through the steps!
This tutorial assumes you are using Automatic Wordpress Backup Plugin and that you have a backup ready to go. For instructions on how to create a back up please see the How to Automatically Backup Wordpress tutorial.
Access Automatic Wordpress Backup
In your administrator section, go to Plugins >> Automatic Wordpress Backup >> Settings.
Scroll down and go to the Restore from a backup tab.
Select the backup you wish to use and configure appropriately.
Restore from backup when finished.
Select OK if you are sure you want to run the restore. A manual backup will be created prior to running the restore in case you wanted to revert back.
Once you click ok, it will run the restore and then refresh once completed. Give it time to complete the restore; the larger the backup file the more time it will take.
That's it! You have just restored your site!
