Thanks for the replies, guys. It turns out that WildBil2Me’s observation was right on.. and I fixed the issue. Although the webhost had upgraded their php recently, they looked into it, tested the site, and found that our site was the only one acting up this way.
WildBil2Me is correct–the permalink structure was borked. I went under the General Options of our site, and I saw that our blog address had the following entry:
“https://www.horror-101.com/index.php”
This was causing the incorrect ‘dead’ urls, as WildBil observed. I erased the “/index.php” portion out of our blog address so as to read “https://www.horror-101.com”…. and the site is back up fine! All our articles and archives are fully readable and all links are working fine!
The issue had been caused all this time by an incorrect setting for the blog under the Blog address setting. Such a simple fix for such a monumental headache! But we learned… we learned!
This issue has been resolved.. Thanks for pointing me out in the right direction, Wildbil2me.
Sincerely,
Armando
