I have selected the "Enable two lines text logo" checkbox. I enter the text logo as shown in your example in the documentation, with a "<br>" where the lines should break. But after saving/publishing, the lines are shown with no line break.
If I go back into the customize section again, the "<br>" has disappeared and I only see a single line of text. I've tried it on different machines and in different browsers. Same problem.
Any help would be appreciated. Thanks in advance.
