Hello

I have some problems with the upgrade. I tried it on my testsystem. It's a little diferent to the live system, but 5.4.0.5 runs with out problem on the testsystem.

Testsystem:
Windows 7
IIS 7.5

I have now following errors:

#ERROR: PHP Fatal error: Cannot make static method AttributeKey::getList() non static in class FileAttributeKey in D:\web\around\concrete\models\file_attributes.php on line 241

-> I removed the slideshow block on some page the error disapper. But some sites show only this error also in the dashboard under the filemanager/Add functionality. Why?

#ERROR: Can not redeclar date_nav...

-> This one is clear... Concrete include the date_nav block in the concrete\blocks. I had the old one installed under the packages folder...

#Problem: Add Block or edit block not longer possible under the edit mode... The loading sign is always showing.
strange...

Any help or informations avaiable for this errors? Maybe it's a problem of my testsystem but yeahh 5.4.0.5 runs fine on it.

Thank you
