Jenny, I tried the link you posted (you can go to the archived link at https://web.archive.org/web/20190201032033/https://www.bigfishgames.com/blog/game-walkthroughs/
for a list of old walkthroughs) but it appears to be dead. It scrolled and scrolled, then finally stopped on a blank white page. I guess that is the "management" issue?
I don't know what it is, but I had it happen to me today.
What you need to do is go to archive.org and do a search for www.bigfishgames.com/blog/game-walkthroughs/
I've found it's faster to go down to the 2nd search box -- the one that says GO next to it, and tick the radio button next to "Search archived web sites" before doing the search. That narrows things down a little.
Look for a date that isn't the most recent because the most recent ones give a "not found" problem. January 2020 worked fine, but I wouldn't go too much more recent than that.
I think the white page problem is caused by the Internet Archive having very old servers, and sometimes they time out or are undergoing maintenance. If the archived webpage from one date doesn't load, try the same webpage from a different date, and it might load if it's on a different server.
Remember that it's better to go to the Big Fish walkthroughs page if Big Fish has the walkthrough up because the Big Fish site loads much fasterhttps://www.bigfishgames.com/blog/walkthroughs/name.a.html
The archive.org website is mainly useful for walkthroughs that Big Fish used to have but where the old link doesn't load and Big Fish's current walkthrough list doesn't list that particular walkthrough. Eventually this shouldn't be a problem any more once Big Fish gets their walkthroughs updated and moved over to the new location.
