I don't really know how to express my problem, so bear with me. This is a bit hard to explain.

I have a Wordpress installation, the latest, and often (once a day) my site redirects users to the /wp-admin/install.php file. Asking for my login credentials of course. I have tried reinstalling WordPress and still have not been able to figure what they are doing.

That happens regularly. Also, a few hours later, I am able to see my site normally. Hope this makes sense.

I suspect there myst be some database DoS that allows them to inject a redirect of some sort into my admin area, thus redirecting the user to said directory (install.php). But that's just me. I really have no clue what else could they be doing.

I looked at the source code from several php files and noted some of them don't include a ?> tag. Could that be an issue?

My hosting company is iPage, I've contacted them and they say there's nothing wrong with my files. Anyone have a clue? I can paste the code to any source file.
