Suppress "Warning: MagpieRSS: Failed to parse RSS file."

If for some reason you really want to suppress this error:

1. Find the file rss_fetch.inc. In my case it was inside the folder "/magpierss-0.72/"

2. Search for the text "Failed to parse RSS file"

3. Comment out the following line:

error($errormsg);


That should do the trick. A dirty fix, but a fix nontheless.
