i tried the update with magento connect, everything works fine.
after that i got this \"error\" in the frontend at the product-page, and 2 other locations.
here is the message.
#1 /htdocs/app/code/core/Mage/Cms/Helper/Page.php(131): Mage_Core_Block_Messages->addStorageType(\’catalog/session\’)
I commented out the addStorageType Call. Is this ok? im not clear what this call does. But everythink seems to be ok.
