errors seen in apache error log

[hn-88]

Apache's error log shows lots of errors like this, though the page seems to display OK on browsers. We're running Moodle 4.5.1 and mod_hvp version 1.27.2

Is this "page did not call set_url() error coming from mod_hvp or is it coming from core_courseformat ?
