I have a bug in my site somewhere that doesn't allow the css to load properly - for one, the page margin should be flush with the header, but as you can see (onandoffthegringotrail.com), there is about a 12px margin of page background to the left and right of it.
Also, when I update something in the wp-admin section, the page comes back blank white and I have to manually go back to it.
Finally, it seems to be taking a long while to implement the css changes.
This seems to have happened after I put the comments and content php files into the child theme for editing. I've also recently added a lot of site support plugins, such as Yoast SEO, W3 Total cache and MaxCDN (content delivery network).
Can anyone tell whats is going on?
Thanks very much
