I have done a full back up of my website and saved it on my dropbox. After that I have reinstalled wordpress. Now I have new WP installation.
I wonder if I can restore my old website with the information in my dropbox?
Yes, you can restore your dropbox backup at your new WordPress installation:
1) install Backup & Restore Dropbox plugin at your new WordPress installation;
2) connect the plugin to your Dropbox Account where your backup is saved;
3) click “Restore” button in front of the backup you are going to restore.
The main condition is that the name of your new website installation should be the same as your old website when you backed it up
