Can you recommend some post upload checks?

  1. Delete unwanted files, like ‘test’, ‘copy of’, etc.
  2. Give write permission (777) to the required folders.
  3. If .htaccess file has been uploaded, make sure it runs according the the server settings. Sometimes .htaccess files run on local but not on server.
  4. Make configuration settings according to server where required, like database connections, file paths, etc.
  5. Do not upload folders required for local copy of the web site like ‘backup’,'db’, etc – if you maintain them.
  6. In folders where there are no index/default files, place a blank index/default file to avoid directory listing. If this is not done, a site visitor can type in the folder path in browser URL and see all files in that folder which is not a good idea. This can also be done using .htaccess file with the following code. Options -Indexes
