Thanks for your report - I hope it wasn't a malicious link! I didn't realize that the SWI-Prolog official website used http and not https, the bad link has been corrected in all 3 instances to swi-prolog.org
Thank you and sorry, I only saw your reply just now, and at the same time realized my correction tip - www. - had been eaten by the markdown parser without me noticing! Good you worked it out anyway. The site didn't seem malicious to me (otherwise I would have said so), just something completely different. Maybe a misconfigured Apache virtualhost or some such.
