not sure if this is of any use, but this is what happened to me and what i discovered…
I started to get the ‘Not Data Received’ error yesterday just all of a sudden (everything was working well before that).
The data I was ‘Updating’ was PHP code typed into my site page.
To narrow down the problem I tried an empty page (no code) and this worked fine so I build back up from there..
I finally nailed it down to this…
As soon I inserted the text “http” or “https” into my code then, bang, it came up with the ‘No Data Received’ error, take it out and it updates fine
Any explanations anyone?
