Yeah, it was the "Enable Cookies" option in my preferences that was un-checked when I started having issues. I enabled it and Marketplace inside Singularity Viewer started working again. I know this was probably just a rookie mistake but I've only been playing SL for almost 4 days now so I'm still learning. Thanks for letting me know how to fix it!
The marketplace inside Second Life isn't loading. It's stuck on a white screen, and when I refresh, nothing changes. At the bottom of the window it shows "Done" which means it's done loading.. which it isn't... Help?
