Hello Mark,

Can you turn on the error reporting for your site and see what is the error displayed. To turn on this: Joomla > Site > Global Configuration > Server > Error Reporting = Maximum. Can you provide us with backend access and ftp access as well so that we can helps you fix this issue much quicker.

Please be advise.
Thanks.

Thanks for that.. I put error to maximum. It showed there was an error with update 1.2.1 . So Deleted all the update folders.. All good now.

Thanks for updating Mark! It's probably because you did install one of the earlier beta's Anyway glad that your issues are resolved now.
