I´m giving up.....
Have restored a backup, done this within 1 week old, same error (aargh) 2 weeks old (same error) (arrgggg) 3 weeks old.. YAHOO it works... (3 weeks
)
But... now i´m up and running...
3 missed updates from this restore/backup :
Acymailing, jce and Joomla 2.5.17.
I installed them once at a time, and testet the shop, and after each other, it still worked 
I regent that the "badges" i created in about this week, have done something, or maybe i have done something.
When i made the discount, i did not follow to checkout, and to the payment-gateway, and that i have learned...
I´m a bit sad for all the cliks/hits and the comment on the pages, but better to have a shop that's works.
Now i´m interested in automatic check to see if site down, shop don´t answer or slow. 
Thanks.. ??? I think...
Regards.
