This is my problem, I'm trying to do some very basic learning of php and sql on my own. I've been doing alright so far on my own, but I have come upon one problem that I can't figure out on my own. I created a few simple pages where the someone can create an account, login, then edit any information they previously entered, then a logout page. Everything works just fine in ie7 and firefox. However I have problems with ie6 and lower. On the first page and the login page, in ie6, after hitting the submit/login button, it just returns a blank page. If I hit refresh, it then displays the page just like it was supposed to in the first place. Both the form and the login in page is where I start sessions, so its probably somehow related to this. How I go about fixing this, I have no idea.
Is this a problem with the way I coded it in php? Related to some of my servers php.ini config settings? Is this not related to php at all, and just another bug with ie that I can't fix at all? Even if this turns out not to be wholly php related, ANY information or direction you could give me would be very, very helpful.
