Yes, same problem here. Can't log in using Opera Mini and Nokia N70. It worked just fine a week ago, or so.. Hope it gets fixed soon.
I have same login problem in my Nokia N800. I press Login button, but nothing happens. N800 has Opera based browser too..
Opera Mini 3.0.6636 + Siemens ME75: same problem. I really hope this is just temporary... What about the "normal" Opera browsers in PCs? Do they also have the same login problem?
I tried to disable JavaScript from N800 opera browser. Now it works!
Secondly I tested Opera browser in my Mac OS X. Login ok, but something goes to Error console:
Unknown thread
Opera has modified the JavaScript on www.geocaching.com (Prototype fix applied)
Please fix this problem..
