Sadly not updated

This worked great back in October when 4.9.8 was out but it hasn’t been updated in a year and leaves something out now.

Using it today caused an issue in the the_excerpt() in the !is_single() loop. The the_excerpt() would not print. I deleted and reinstalled the whole wp installation several times with no success.
In is_single() the post would print great.

Using wp 5.1.1 & php 7.3.3

One star because it’s included in a new install of wp and isn’t up to date.
Like I wrote, last fall this thing worked like a charm.
