Installed v11.009 and started process of updating sites one by one. Exported first site from pro 10. Custom template. All ok except footer. V11 added a tiled image to the footer so you could not see the backround color I had defined in the template. When the image was removed everything ok here, but it is not true that template conversion from 10 to 11 is without problems and needs to be checked carefully.

This first site conversion also has shopping cart. When checking Shopping Cart propertie sin 11 when I left the page got error message that e-mail address was wrong (adress orders are sent to). Here we had 3 mails seperated by semi-colon and worked fine in v10, but now v11 only accepts to have one mail address here despite the help stating you can use multiple if semi-colon seperated.

Now I stopped this and other conversions from 10 to 11 because we must have orders sent to multiple mail addresses.
