Last week, I realized that there was an error with BlogCampaigning's RSS feed. Although some feedreaders were still able to grab the content, others were getting XML Parsing Errors. As I often do when I get a warning message I don't quite understand, I Google it. Chances are, someone else has had the same problem as me and figured it out.
Quick Online Tips helped me fix the problem. The error was caused by some blank spaces in one of my .php files. Since I often muck around in the theme, this could easily have been caused by me or one of the plugins I added.
Going through thousands of lines of code didn't seem like a good way to spend my afternoon, so I installed the Fix RSS Plugin. It scanned all my code, and quickly fixed the error. While the appeal for a $4.99 donation to the creator of the plugin is the first time I've seen something like that in Wordpress, I think it is worth the money.
The lesson to learn here is that even if you think your site is working perfectly, other people might be having problems with it. After making any major changes, you need to thoroughly check to make sure everything works (or have a good team of writers that occasionally check things for you).
Thanks for reading BlogCampaigning—and if you notice any other errors, let me know!
