 In PHP 8.0, when accessing the non-posts/pages like /data/feed and
 /data/rss, it shows an PHP Warning error saying "Attempt to read property
 "post_title" on null".

 This fix added an isset check for the variable and immediately return
 false value.

 I have a pull request on your mirror github page, which shows the possible
 fixes for this error:
