Nothing really works with my 18.104.22.168 version (as it seems).
I became desperate and installed the V 22.214.171.124 in good hope this will cure the flaws mentioned before with the order system
The old shop is still up an running as I installed the new version in a separate folder.
I copied the actual SQL database and renamed the copy for the latest magento version to reuse all the data.
Upon opening the new shop, I got the following error messages:
Recoverable Error: Argument 1 passed to Mage_Core_Model_Store::setWebsite() must be an instance of Mage_Core_Model_Website, null given, called in /home/.../app/code/core/Mage/Core/Model/App.php on line 427 and defined in /home/.../app/code/core/Mage/Core/Model/Store.php on line 279

Line 427 of App.php:

Line 279 of Store.php:

I also tried in the install menu of the .4 version to use the existing SQL database name and password. It rejected it stating this DB already exists. Why is this not possible? It would be the easiest way to reuse an existing DB with a new installation of the latest version.
Can someone urgently give me a hint on what to do?
