The process was completely different and based on the subsite .be before installing HMWP and influencing those links. Of course after you have set our multisite network to the default version to resolve what HMWP has caused, we lost the work which was done by a developer and which keeps the process exclusively into the subsite .be or .fr or else..
I hope you’re going to assume fully your part of responsibility. This issue has taken lots of time and efforts. We hope this problem will be resolved soon and once for all.
