[solved] "no json object could be decoded" error on GUIMiner

[taltamir]

Using GUIMiner I was getting the error code "no json object could be decoded" and couldn't find any info about it. I eventually figured it out, its what you get when you inputted username/password is wrong (at least, when using BTC Guild; which incidentally wants you to input worker id and password not your general id and password).
