Whenever I got to http://example.com/wordpress/wp-admin/options-permalink.php my config file at http://example.com/wordpress/web.config instantly gets corrupt and I have to delete the config file. What could be causing this? I am using the newest version of WordPress and am running it on IIS 7 on Windows Server 2008 R2.
Permalink options page corrupts web.config file
When visiting that page it would actually create an empty config file. To fix the issue, I copied the config file from my http://example.com/ directory to the http://example.com/wordpress/ one, it works fine now.
