I'm using HM 4.0.1 for website development. I've been struck with a strange scenario. I'm getting error message of ' cannot open the site', see figure below. I do understand when does it appear and how to avoid it, but I'm unable to understand the reasons for this error.
Apparently, it seems that error is in Hierarchical Menu, but on the other hand it is in HTML Page.
Any help will be greatly appreciated.
