RSS feed not working, how to fix it?

Your theme is version 2.9 but the current version is 2.9.5 so consider updating. Take a backup before starting.

“http://pugle.net/blog/feed/” has a 302 redirect. This means the url is redirecting to itself in a continuous loop. A possible cause is an error in .htaccess. This is a hidden text file in your /blog directory. Can you debug it? If not, try renaming it using FTP, then go to Admin page / Settings / Permalinks – reset to your preference and Save changes. WordPress should make a new .htaccess for you. There might be other lines in your current .htaccess but I can’t see or comment on those.

If your site gets messed up, go back to the original .htaccess.

If your site is OK but the error returns, the problem could be one of your plugins making changes to .htaccess. If so, deactivate them all and then reactivate one at a time until you can identify the offending plugin.

You should have started a separate thread because your solution is different. However, the answer is to put “feed/ at the end of the url, for example:
http://artofvideo.ca/category/indian-wedding-photography/feed/
Its usual make this into a link around an RSS icon.
