If you've just uploaded your site or made some changes to it this could be a caching issue with your browser. Follow our guide to clear your browser cache and this should normally fix the issue.
If this doesn't work, make sure the names of your website files are all in lowercase as our web hosting server is case sensitive. This can mean that if the homepage of your site is called ' Index.html' instead of ' index.html' it may not load when you first access the site.
Lastly, check that the files you can't see are actually there by using FTP. If you find anything missing just re-upload or re-publish your site and you should find they'll come back.
If none of the above works please use contact us to get in touch and we'll do our best to fix it.
