sorry for a delay we have been testing the issue and found a small bug related to https protocol deep down in the MonoX Core inside the localization and SEO handlers. The best way to solve this issue would be to upgrade to patched version that I can send you, is this an option for you ?
What MonoX version are you using ? Patch would be the 4.5.3xxx version.
Also you can override the "Back link" generation and set your own but then you need to take care of many things that are already implemented on MonoX side, such as SEO, Localization, Discussion parameter handling etc.
Let me know how you want to proceed ?
