Hi Nev,
I tried to make new friend request and 'Invite Friends' to the site as well. However, I am unable to replicate your error. Am I missing something here?
I have also checked your backend and there are editor plugins in published state.
If you are still hitting this error, can you provide some screenshots of the page where you encounter the error? Also, can you provide us super user access so we can troubleshoot the issue more efficiently? Thanks.

Hi Raymond,
I activate Tiny Mce and the editor has now appeared.

However I may be experiencing send issues.
Will get back to you as I need to do some more work.

Regards,
Nev
