I think Joomlapolis and other extension developers need some more credit.
Especially from people who don't support them.
Joomla changes a bit too fast maybe.
Maybe Joomla should set a new version available for extension developers first so they can adapt in time and don't get the blame of their extensions not working.
The CORE has changed so have patience for extensions to adapt!
I have the same problem as many others, but i don't think that most website owners live from their website using CB or other extensions. Certainly i don't. So i will be patient and look for an other solution now, like fall back to joomla 1.6.5.
Give some credit or support the developers.
I'm right now not in a position to support them, so i'll have to wait.
But when i'm finnancially in a better position, i will support this great Extension CB = Completely Brilliant!
By the way. In case fall back to joomla 1.6.5 is too diffucult or impossible for you.
You could enter your database webadmin and disable cb core and plugins/modules so your frontend is visible normal again. But your users can't enter the way they normally do.
So now you can put a message on that they have to wait a little while.
Uhmm.... is downgrade to J1.6 a solution. (or restore your backup?)
