Below, we'll show you how to change the Text Separator.
Find the Text Separator setting. Depending on your Joomla version, it should be under either the Module tab or the Basic Settings tab.
Enter a value here, such as a forward slash. Then save the change by clicking Save in the top menu.
Below are screenshots showing how the change we made affected our breadcrumbs:
|Text Separator left blank|
|Text Separator set as /|
