Domain mapping does not seem to work correctly at all.

Domain mapping does not seem to work correctly at all.

Primary site: rtl.omnisocialmedia.com

- rtlenglish.com - maps ok, but site will not finish loading
- rtl.edu.hk - broken theme, non-stop loading
- rtl.hk - broken theme, non-stop loading
- readytolearn.com.hk - does not map at all
- readytolearn.hk - broken theme, non-stop loading
- rtlenglish.co.uk - broken theme, non-stop loading

Please can you tell me what the problem is?

Thanks
