Hi,
Firstly, you can try restoring to a previous version of your site. In order not to delete what you’ve already done, I recommend duplicating your site before restoring it so you have 2 versions of the site under your account.
As for your question, only Wix Employees have access to your site but we don’t publish any changes if made. Note that you can also import the information in order to speed up the process (if necessary):
Have a good day,
Tal.
