Hi Rene, 

In your new site, scss file didn't be compiled correctly.

Please go to your new site admin->theme options, and click the "Save Changes" button again.

Then, new site css file will be created again. 

We have done these steps again on your end, So everything is fine now.

Please check your website again on your end.

If you have any other questions, please let us know again.

Best Regards, C-Themes

So I don't need the following site: https://bombandboujeeboutique.com/

The client has decided to go with https://bombnboujee.com/ so the other site will be obsolete.  That said, I worry that the new site will have a problem and develop a strange appearance (as seen on the old site).  Can you help me understand why this happened on the old site?
