404: We can't find what you're looking for.
Hey there, user! It looks like you've found yourself in a little bit of a dead end.
You tried to get to /EN/printshopmail-connect-user-guide/1.4/designer/Interface/Pane_master_properties.htm which, unfortunately, doesn't seem to exist.
I mean, I even tried snooping around to see if that page existed somewhere else, no dice there. So I give up here, sorry.
But fear not, I've logged this bad little link somewhere and will take a look at it to see if I can fix it.
In the meantime, hit the links on the left and navigate to what, presumably, is the documentation you were looking for!
