We are aware of the editor not working properly & you not being able to use the "image" button to add images to your post.
The gallery will be getting an upgrade to fix that issue in the next few days. Please bear with us.
We are also aware of the "You don't have the correct permissions" error when trying to view attachments. This is also being looked in to .
Thank you for your time,
Gingerscraps IT Department
