Hi There @dirtyfrenchgirl
Thanks for writing in! Upon checking, I see that you have enabled maintenance mode for your site. Could you please disable it temporarily, so that we can look into your issue.
First of all, make sure that you're fully updated by checking the version numbers from here (https://theme.co/apex/forum/t/troubleshooting-version-compatibility/195).
In the meantime, copy all of your custom CSS rules into an online tool like CSS Lint (http://csslint.net/) and see if you're getting any errors. If you see any errors, you need to correct them to parse your CSS correctly.
Also if you have any caching plugins, you need to purge your server cache and clear your browser cache before testing your changes.
