Staying logged in is related to cookies. If you log in and vb3 is able to properly set a cookie in your browser to remember you're logged in, then everything is great. If vb3 cannot properly set the cookie, then you're logged out as far as its concerned. WWW sites can set cookies so they expire when you close your browser or at a specified date and time in the future. When you click the "remember me" checkbox when you log in, vb3 sets the cookie to expire some really long time in the future. If you don't click the checkbox, it sets the cookie to expire when you close your browser. Every time I have worked with a site user who's complained about this kind of thing, it is some software they've installed on their computer. Like zone alarm firewall software. If you are blocking cookies (a setting in your browser), obviously the login isn't going to work right. My recommendation at a first thing to try is to clear your cookies. The various browsers have different pulldown menus to do this. In chrome, CTRL+SHIFT+DEL brings up the "clear history" dialog. You only need to erase your cookies (you need to look at what's checked on that form!). In IE8, tools menu -> internet options, Browsing history tab (first one), delete... button brings up a similar form. In Firefox, CTRL+SHIFT+DEL also works, or tools -> clear private settings.
As far as IE8... I posted at vbulletin.com about the problem. Let's see what they say about it. I tried the site with IE8 and I don't get the duplicate messages but I do get "your post is too short" if I use the quick reply box. BTW, these last two posts from Chrome and not any hint of a problem. There was some leftover code from the checkbox I implemented for the fixed width scheme that I removed, and that seems to have fixed chrome.
It happens to me when I post using my laptop (IE), but it doesnt happen on my work PC (Chrome or IE) or home PC (Chrome).
I found that bad boy and snuffed it. If anyone has issues with the double post or message too short, you'll need to clear your browser cache and all will be good. It was a line of javascript I added to one of the templates to support the checkbox width toggle that I forgot to remove when making the site fixed width.
Yeah, I'm happy the site is working again. BTW, it was when I made the site go back to fluid that I removed all my checkbox/toggle width business but that one line in the skin.
