Hi,
Do I have to correct the permission settings on the copied Folders ?
I'm using ACL's so only a specific group should be able to edit pages.
When PHP/DokuWiki doesn't have read/write access on the data directory, the wiki becomes read-only...
Yes, you have to correct the permissions. Eventually, take a look at
https://www.dokuwiki.org/install:permissions
DokuWiki ACL have nothing to do with file permissions, so everything will be ok.
