Thanks for all this information, guys. I summarized everything I read in this thread to GoDaddy — asking to be whitelisted. They gave me a solution that worked (for me at least). It goes like this:
1. In you wp-content folder; add the suffix “.disabled” to your themes and plugins folder eg: themes.disabled / plugins.disabled
2. wait a good ten minutes
3. remove the suffixes
It is true, their security features are a little overzealous and limit the amount of activity a certain IP can do. It will eventually be remedied, but this works in the meantime — so far.
