Thank you so much Tom for your reply.  I changed the setting to SFTP as you showed.  I now get a different error message.

If you (or anyone else) have further suggestions to help resolve the issue of not being able to publish changes, I would be hugely grateful.
Thank you.

I am unable to publish changes to my website. The error says " FTP has been disabled. Use a SFTP connection instead."

I have spoken with IONOS who is my domain host. They tried a new SFTP connection but say that WebPlus x 8 does not meet security standards and therefore I am unable to publish new updates to my website.   

Is there a solution to this so that I can continue to use WebPlus x 8? 


Thanks
Gill
