I'm sure a lot of you are wondering what have happened to my blog right? To all my blog subscribers, my apologise to you guys. I know you haven't receive any updates from the feed of my blog for quite a while right? My blog feed doesn't even updates itself in your blogroll righ? According to Feedburner, my Feed is not valid. Huh? Of course I have tried and tried and tried...but all my efforts are futile. I have tried to google about this error but to no avail. I'm really clueless right now. Can anyone help me? :(

Ouch! My head hurts!

Feedburner's Feedmedic reported that there is a problem with my feed that reads, "Your server is sending us some non-XML data. This is usually caused by your blogging platform or server generating an error page that is not in a valid feed format (usually it is plain-text, or HTML). Please confirm that your source feed is working properly." and "Error getting URL: 400 - Bad Request" What could be the source of the problem? Can someone show me the light please?

Then when I try to look up for my feed address: http://www.tekkaus.com/feeds/posts/default?alt=rss, it will navigate to http://feeds.feedburner.com/blogspot/tekkaus. The the eeror message pops up telling me that Feedburner cannot locate the feed!

The problem started when I migrated my blog address from blogspot to my own domain (http://tekkaus.blogspot.com-->http://www.tekkaus.com). Then all hell break lose. Since then my blog feed is experiencing problem. Is it has something to do with blog hosting? You see, although I have my own domain...I don't host it myself. I am still using blogspot to host my blog. Could this be the source of the problem? Anyway I will really appreciate it if someone could help me with this. *Sob! Sob!* Hopefully this problem here can be solved as soon as possible. I will try to seacrh for the remedy this few days guys. Wish me luck! If you can help me let me know yeah!
