When writing the post Stop your laptop from succumbing to thermal death I wanted to upload a text file which could be downloaded by the readers. The file didn’t have any extension and as such was not accepted by WordPress when I pressed the Upload button.
I decided to upload the file with the File Manager which is accessible from Hostgator’s cpanel. When doing it, I discovered that various folders which belong to olivetalks’s WordPress installation can be easily seen in web browser by editing the URL in the address bar. For example, olivetalks.com/wp-content/uploads/ or olivetalks.com/wp-includes/
Currently these links are already fixed but here’s an image of how this was before:
Check your own WordPress blog, it’s possible that you will encounter the same issue even if your WordPress installation is not hosted with Hostgator.
Now that I got your attention, here’s a short description of how to fix this problem. In the main folder of your WordPress installation (the one which contains three folders wp-admin, wp-content and wp-includes) find file called .htaccess (dot at the beginning of the name is important). If the file is not there create it (and set the permissions to 0644). In any case edit the file and add this line:
Options -Indexes
This line will tell Apache (the most popular web server) not to show listings of directories. The configuration applies to the folder where the .htaccess file is located and recursively to all its sub-folders.
After updating .htaccess file – if you try any of the problematic folders you’ll see that their content cannot be seen any more:
Now it’s all right

You wouldn’t happen to know a reliable source for setting up Thunderbird do you? I have found a TON of resources and none of the screen shots match what TB looks like now. I printed this post, excellent. Cracked me up!!! About the Inodes or whatever they were (some other post of yours).
