Hello Dirk,
I am sorry for the delay of this reply as now is a weekend for us here
Regarding your issue, em, do you think by any chance you can mimic your live site into a testing site so that we can install EB 5 again on your test site and we will look into your issue again?
To be frank with you, we can't replicate your issue at our end so we need to investigate at your site in order for now to identify the cause of your issue.
Please advise.
