Hyperlinks failing

On the sticky at https://www.bergiesplace.com/Newsite there are three hyperlinks: one for my photo galleries, https://www.pbase.com/bergiesplace; one for my blog, https://www.bergiesplace.wordpress.com; and the third for my cat’s webpage, https://www.pbase.com/bergiesplace/pearlswebsite. The first two work fine; the third jumps to a blank screen on which the original link field is empty. Do I conclude correctly that text hyperlinks won’t work for a lower nested file? That is, it will jump to …com/bergiesplace but not further to …com/bergiesplace/pearlswebsite
