Firstly, total newbie here, so please excuse me if I am raising something which has already been covered elsewhere... (and yes, I did search beforehand).
I am running Joomla 1.5 (nightly build) here on a local Linux+Apache server. Using the "standard" template with 1.5, I can register new users from the frontend with no issues. When I make "BEEZ" the default template however, my test users get a 403 error when they click on the "submit" button when they try to register.
I probably have some configuration issue here, however on previous test installs of Joomla (ie the stable 1.X family) there seems to be no problem. I have also done test installs of Mambo as well (just to test, you uderstand

Interesting that changing the template can break the registration process? I would be interested in any comments you might have on this - hopefully you have seen this problem too.
Thanks & best regards
