Oh really!? Cool. I'll give Chrome a try. Seems like I was having some other problem in chrome though. But I'll try it.
One other thing - just in case this info helps... I just copied the database of the site where it didn't work over to the database of the site where it did work, and that site stopped working after I did that! So it leads me to think it's something in the database. One difference between the two sites was the plugins I had installed. So I thought maybe it was a plugin. So I deactivated all the plugins (on the site where it used to work before I copied the bad database over) and that didn't have any effect.
And yes, I'm really surprised no one here has any idea about this. I've seen many other people mention that they were having this same problem. Thanks for posting your latest info Shazzle!
