Open local links in a link button in the current tab
A link button with a local link like "/pages/testpage" should open the page in the current tab and not in a new tab.
What version of COYO do you use?
@Sven Hoffmann I can't find such a tick, there only the option for Name, URL and Design and a Preview of that button.
When creating a link button widget you can remove the tick at "Open in new window?". That should do the trick.
Does this solve your problem?
Or maybe it should be able to define that in the button's settings.
