Kentico MVC - PageBuilder Error on external Staging site

Question

Am using Kentico MVC v12 Service Pack.

Have enabled Preview feature and PageBuilder in Application_Start. When running from localhost, can successfully edit relevant pages using PageBuilder as required.

However, when ran from a staging site, which is a clone of the localhost version, I am getting an error in the Site settings when I try to add a Presentation Url (I am definitely adding in a valid format with the starting "https://" included), which is required for the PageBuilder to be used in the Pages application, where I see this error:

An unexpected error occurred, see event log for more details. Event source: PageEdit, Event code PreviewLinkGeneration

Any assistance would be much appreciated. Thanks.

That error is basically only looking at the string of the URL (almost like a simple validation). Are you sure there is no whitespace before the value you entered in? I can re-create your issue if I type in a space character before the URL.

You can also try clearing the field and saving the form. Then re-enter a value.

If it is still not working, try re-signing all your macros in the system as I have seen the regular expression validation rules have issues if macros aren't working. Which is really what this check is:
