I've upgraded an EPiServer CMS site from 7.5 to 9, upgrading source code and DB. I don't necesarily need to migrate the Media files.
After the upgrade, everything looks to be working fine, except when I try to add images, documents or try to create blocks.
When adding an image for a page, it fails with the following error: Content type "ImageFile" is not allowed to be created under parent of content type "SysContentAssetFolder".
When I try to add a global Content Block, none of the block types appear. When trying to add it in a content area, there is no button to add new ones.
I've found that if I explicitely allow the Content Type (ImageFile or the content block) under a page type in the tblContentTypeToContentType table, it works. Nevertheless I don't think that the right aproach would be to add permissions one per one. We didn't need to in the 7.5 version.
Hope someone can help with this.
Thanks in advance!
