With Easy Blogging Wizard setup so that the first step is the "blog.php" payment option screen from pay-to-blog, on first login Easy Wizard will load and provide Welcome page with steps. If the user goes to any other step (trying to skip payment) they are hit with an infinite redirect loop in firefox. Normally, pay-to-blog will always redirect to blog.php regardless of what the user selects.
Also, kinda odd, but if you're using the Genesis framework, their sidebar menu will show even when pay-to-blog hasn't received payment (all other admin navigation is missing). Must be something in the way they add their sidebar navigation. Just thought I'd mention it.
