I am currently working on Robohelp version 2020.6.76 and generated a frameless output of our online document only to find out there seems to be some text (Hyperlink to Index .html) that is being displayed on top of an image in the Skin Home Page in the top right-hand corner.
When viewing in the Browser window and inspecting the code, there seems to be a hyperlink to an index which I cannot locate within Robohelp settings to remove?
index.htm is typically the start page of a the help. By default the logo in the skin links to the start page (index.htm). While the image is hard to read, it looks like the code is appropriate for the header logo. Did you customise the skin and move the logo and project title to the right?
