When I upload to FTP host, there is showing an error msg (check the image )
and also page is not showing after published... its going redirected to here --> Enable or disable cookies - Google Account Help
Can you please try uploading a blank new site with the same credentials and domain and see if it goes well?
I tried to upload a blank site.. but that time showing some msgs back to back..--->
something like this 2,3 more msgs were came (museconfig.js , jqerry.watch.js)... and its took too much time (around 20 mins)
Is this coming every time you are uploading or just once in the beginning?
no.. sometimes only
If it is happening intermittently then we can assume that there might be some corruption in the files already uploaded to your host.
Just reach out to them and ask to delete all your site files from their server > re-upload the site and it shall be good.
Let me know how it goes.
