I have established the online CMS on my main domain and on a sub-domain. On the main domain it works just fine. On the sub-domain I have troubles creating new files and uploading images. Opening a new file does not show the relevant front matter, and for uploading images it is not possible to select a resource folder. Also the preview function does not work on the sub-domain. To illustrate the issue I have uploaded a few screenshots. I would be grateful for a hint how to overcome these issues.

You have define the frontmatter for each of the folders.

If you haven’t defined an image field for the folder, you aren’t shown the field in a new file. Is this what you mean by “for uploading images it is not possible to select a resource folder”?
