Problems adding new posts, replying to them, deleting posts as administrator, and signing out

[Annabel Gregory]

Has anyone else been having these problems?  Just sent this to Ning Support:

I and others have been having problems over the past week adding new posts to our site, deleting posts (as administrator) and signing out. Some have been having problems with replying to posts. When you try to add a new post, the row of icons at the top of the box is not there, so you cannot add links, images or etc.
This seems to be a problem on some Macs/PCs/phones etc and not others, but this varies.
