This is all very interesting.
First, I tried installing WordPress manually to my shared windows hosting on Godaddy, and got the 500 error. Searched around and found information on it similar to what is in this thread.
Then, I decided to let Godaddy go ahead and install it using their "click to install application" type interface, and then just add back my content manually. Thought that might be the best way, since they might have some specialized setup routine that I'm not privy to... It worked fine for a couple hours, but then it started slowing down... giving blank pages... and then 500 errors... cleared up a few hours later... then down again... Round and round it goes.
It's not as though this site had any traffic other than myself editing pages, so I'm thinking that perhaps there's too much of a load on their servers, perhaps? I checked the log files and couldn't find anything pointing out the error, so I'm at a loss.
This is kind of a shame because I have a lot of clients that want WordPress sites and having them register their domain and host in the same place seemed like a fantastic thing, but I can't recommend Godaddy hosting for WordPress if the sites created will be randomly down. On a side note, I did ask a question about WordPress configuration to the email help desk and was given the "We don't support 3rd party applications" response. I suppose it's understandable, but you would think there would be some sort of support for WordPress , given that it's listed as a "Product" you can buy with "24/7 Email, Phone & Web Support".
