This is likely a miscellaneous issue, but I have encountered an odd bug - keeping in mind I am in the first week of development, but this is recent.
While working within Firefox, I am no longer able to change the theme. I change the theme, accept the changes, but the new theme has not updated. It continues to display an old theme, even on the few occasions when the new theme has been accepted. Refreshing window, dumping cache is having no effect.
Internet Explorer is having a better job of displaying the new themes but is no longer allowing me to log in. I log in, I am accepted as logging in, but I am still seeing a guest menu. No ability to go into Admin mode.
Did something corrupt? This is weird. If I revert to factory settings, will I lose ALL settings? Ouch.
Clear your cookies. Don't use the factory settings button unless you are sure you need to. It's quite a drastic measure.
Post a link to your gallery for a start...
Thanks guys. Clearing cookies did the trick.
