This is connected directl to this issue, but it relates to all the other ‘cache’ support requests I have sent in most recently.
I have removed all cache tools, except Cloudflare which has been placed in development mode.
And I moved the custom.css file to the parent there.
The moment I did that and cleared cache I got the results…the width of content was 50%
Then I changed the custom.css file to 79% max width, then cleared cache, locally, purged on server
and the content is 50% See here: https://screencast.com/t/NPTyzjhZ0
