Why upload files to businesscatalyst ?
There are no upload problems.
"uploading file index.html, click Resume to try again. this problem persists, try again later."
Click resume, it's still the same error.
And when editing this file, the same.
Upload to BC to check, if there´s an error from any element like 3rd party widgets or anything.
It´s not getting crawled by search engines. Nobody knows the address, except the people you involve.
